HOW THE LINK 2000-R CHARGES
See page 18 of LINK 2000 manual for details of the Ideal Charge Curve.
The LINK 2000-R uses the Ideal Regulator Output Module to control the alternator
to conform to the Ideal Charge Curve’s four defining cycles; Charge, Acceptance, Float,
and Equalize. The following discusses details of each of the cycles.
NOTES: 1) Terminal references for the Ideal Regulator Output Module.

2) Voltage values given are for 70 °F and liquid lead-acid batteries.
TURNING THE REGULATOR ON
The regulator is turned on by supplying 12 V or 24 V to the REG ON (brown
wire) terminal.
It must have power only when the engine is running. See page 13.
DELAY START-UP
Behavior: No output on the Field terminal (blue wire).
Two-second delay allows time for the engine to start.
RAMPING UP
Behavior: Output of alternator increases over a 20-second period.
Ramping up the alternator output avoids shock-loading the belts with full
alternator output. The output on the FIELD terminal is increased over a 20-second
period until the alternator current limit (default value 100 A) is reached. The Charge
Cycle now begins. If the acceptance voltage is reached before the current limit,
the Acceptance Cycle begins.
CHARGE CYCLE
Behavior: Alternator current at maximum and battery voltage increasing.
The Charge Cycle ensures fast charging without alternator overload. The
alternator current limit will not be exceeded. The FIELD output is varied to hold
the alternator at its current limit until the acceptance voltage is reached. When the
acceptance voltage has been attained by either battery, the Acceptance Cycle begins.
ACCEPTANCE CYCLE
Behavior: Battery amps falling, voltage at 14.4 V for 12 V systems, 28.8 for
24 V. (Voltage depends on battery type and ambient temperature settings.)
The Acceptance Cycle guarantees thorough charging by continuing to charge
the battery until the charging current becomes a small percentage of battery
ORANGE

capacity (2% default). The alternator output is varied to maintain the battery at
the acceptance voltage. During the Acceptance Cycle the alternator current limit
will not be exceeded even if a heavy load is placed on the system.
When the batteries have reached the acceptance voltage and the current is
below 2%, the Acceptance Hold Cycle begins. If the Acceptance Cycle has lasted
3.5 hours, the Float Cycle begins, even if the charged parameters have not been
met. If the voltage of either battery falls below the acceptance voltage for more
than two minutes, the Charge Cycle starts again.

ORANGE
LED ON
GREEN
LED ON
ACCEPTANCE HOLD CYCLE
Behavior: Voltage at 14.4 V (28.8 V for 24 V), battery amps below 2%.
The Acceptance Hold Cycle ensures that the battery has accepted as much
charge as it can. During the Acceptance Hold Cycle the charged voltage is
maintained and charging current is monitored. Both the charged voltage and the
charged current % must continue to be satisfied for 10 minutes for the Acceptance
Hold Cycle to end. The Acceptance Hold Cycle is also terminated after 20
minutes from its beginning even if the battery current has not stayed below the
charged current for the entire time.
If the voltage of the batteries falls below the charged voltage for more than two
minutes, the Charge Cycle starts again.
FLOAT CYCLE
Behavior: Battery amps below 2%, voltage constant at 13.5 V (27 V FOR
24 V). (Voltage depends on battery type and ambient temperature setting.)
During the Float Cycle the float voltage is maintained. The alternator will
supply up to its current limit to maintain the float voltage and supply DC loads.
RESTARTING THE CHARGE CYCLE
MANUALLY: The Ramp Up Cycle may be manually restarted by turning off
the REG ON terminal and turning it back on again. This will require you to turn
off the key switch supplying REG ON or shutting off and restarting the engine
if REG ON is supplied by an oil pressure switch.
AUTOMATICALLY: The Charge Cycle is automatically restarted if the
voltage of the battery being charged drops 0.2 V (0.4 V for 24 V) below the float
voltage (0.3 V when charging with the inverter/charger) for more than two minutes.
RED
LED
FLASH
EQUALIZE CYCLE
Behavior: Battery amps constant at 4%, voltage is rising to a maximum
of 16.0 V when charging with the alternator and 16.3 V when charging with
the inverter/charger. (Limited to acceptance voltage for gelled batteries.)
To start the Equalize Cycle press the SETUP BUTTON for five seconds until
the LED begins to flash. Now press both the VOLTS and the A hrs BUTTON
simultaneously. Hold them both down for five seconds until the red CHARGE
LED begins to flash and the “E” in the display goes out. To terminate the Equalize
Cycle and force the system into the float cycle, repeat the same procedure. The
cycle automatically terminates 3.5 hours after initiation, or when the current drops
to 2% of capacity at 16.0 V. (Equalize terminated in eight hours if using the
inverter/charger.)
The Equalize Cycle is a controlled overcharge to remove lead sulfate that is
not removed during normal charging. Liquid batteries should be equalized about
every 30 days when in deep cycling service.
5
EQUALIZING CAUTIONS!
Turn off sensitive electronics before equalizing.
Equalizing causes the battery to gas. You should check the battery electrolyte
before and after equalization. Do not over-fill before equalization as the electrolyte may
expand and cause it to flow over the tops. You should be present during this type of
charging. Hydrogen and oxygen gas is generated during equalization. Make sure
there is adequate ventilation.
Batteries should not be equalized every charge/discharge cycle. Normally, the
battery is cycled between 50% charged and the 85% to 95% charged level reached by
the normal Charge and Acceptance Cycle. Every 30 days, though, the batteries should
be equalized to regain full capacity and extend life.
To equalize, first go through a complete Charge and Acceptance Cycle. Check the
electrolyte level, but do not overfill. Re-check and top off the electrolyte
Remember, equalizing is constant current charging with a small regulated
current that permits a higher maximum voltage. The goal is to use a small current
and gradually let the battery rise to its maximum voltage.
EQUALIZING GELLED BATTERIES
Gelled batteries are not normally equalized. However, if the battery has been
severely discharged, the voltage of the battery may easily reach the acceptance level
with a very small current. In fact, the current may be less than the 2% required to terminate the Acceptance Cycle. This can cause the system to believe that the battery is full
and switch to the Float Cycle. Equalization may be the only way to get the battery to
accept a charge. Be sure that the battery TYPE # is set to #1 or #2 before using this
cycle on gelled batteries.
voltage but the cycle lasts for 3.5 hours. (Eight hours if using the Freedom charger.)
Please consult your battery manufacturer regarding the appropriateness of this cycle
for their batteries.
The equalization voltage is limited to the acceptance
after equalizing.

SPECIAL SETUP FOR LINK 2000-R
The following is a list of special setups that may be necessary to tailor the LINK 2000-R to
your system. Please see pages 10–14 of the LINK 2000 Owner's Manual for details on
how to use the FUNC mode.
F10 - ALTERNATOR CURRENT LIMIT
DEFAULT = 100 RANGE = OFF, 30–220 AMPS STEP = 10 A
This function is only used with the Link 2000-R (Alternator Regulator Model). It sets
a safety current limit for the alternator. This limits the maximum amount of current that the
alternator can deliver which in turn reduces heat and wear on belts and bearings. This value
is reset to 100 amps in the event of a reset to factory default values.
CAUTION: OFF defeats this safety feature and the alternator will be run at
full output until the Acceptance Voltage is reached. You can also use this feature
to troubleshoot the alternator current measuring/limiting feature.
F11 - BATTERY #2 USED FOR CONTROL
DEFAULT ON = BATTERY #2 USED FOR CONTROL
OFF = BATTERY #2 IS NOT USED FOR CONTROL
This function is used to defeat Battery #2 as a part of the charger and alternator
regulator control functions of the Link 2000-R. This is necessary for systems that have
both 12 V and 24 V batteries. Battery #1 must be the battery that is used by the Freedom
Inverter (or charged by the alternator when controlled by the Link 2000-R). You may also
wish to use this function if the main house battery (Bank #1) is substantially larger than
a separate engine battery (Bank #2) that is also monitored by the Link 2000-R. This will
prevent the Link 2000-R from making a premature transition to float based on the smaller
engine battery meeting the charged parameters substantially before the house battery.
NOTE: Function F11 is not changed in a reset to factory default values. If you
wish to change this function you must use the setup routine to change it.

REQUIRED READING
1) Read the REQUIRED READING section of the LINK 2000 owner's manual.
2) All wiring to the terminal board should be #16 AWG (#14 may be used).
The same 8 wire twisted pair cable recommended in the LINK 2000 manual may

be used for the LINK 2000-R. The wiring diagram is color coded to this cable.
CAUTION! YOU MUST READ THIS SECTION!
4) The LINK 2000-R Ideal Regulator Output Module is designed to replace external "P"
type regulators. If your alternator is internally regulated, modification will be necessary. The
LINK 2000-R is
regulation by switching in the negative supply to the field. This includes most Japanese and
internally regulated alternators. If these alternators are to be converted to external regulation
you must disconnect the internal regulator and the diode trio in the alternator. This
should be performed by a qualified alternator shop. The warranty does not cover the
alternator, batteries, or any other devices, or equipment in the system.
improperly converted alternator may cause damaging high voltages. Please be sure
to check the regulation voltage during initial operation to verify that the LINK 2000-R
is in control of the system.
5) The LINK 2000-R is designed to regulate alternators up to 230 amps, provided that
the field current does not exceed 10 amps total. It can also regulate two alternators in parallel,
charging the same battery, if they are the same size with a combined total capacity of less
than 230 amps, and combined field current less than 10 amps. If the alternators are on
different engines you must install a normally open oil pressure switch, or a relay activated
by the key switch, in series with the field of each alternator to avoid supplying field current
to an alternator whose engine is not running.

WIRING INSTRUCTIONS
Refer to the wiring diagram while using these instructions.
There are several components to LINK 2000-R METERS:
4) The Monitor Terminal Board: The
wiring for battery monitoring terminates
here. The ribbon cable from the meter
plugs into this board. It also has a RJ-45
jack on it for the Ideal Regulator Module.
5) The Alternator Shunt: Single 500 A,
50 mV shunt used to measure current
flowing out of the alternator.
These two cords are not interchangeable.
i4.40
1) The LINK 2000-R
Meter: Contains the micro-
processor and display. The
actual regulation program is
in the meter. It is terminated
with a ribbon cable. It also has
a RJ-11 jack for the remote
cord to the inverter/charger.
2) The Ideal Regulator
Output Module: Supplied
with a harness that connects
to the alternator. There is
also a RJ-45 jack and plugs
for the alternator shunt wiring
and red and green indicator
lights used for troubleshooting.
3) The Battery Shunt: Dual
500 A, 50 mV shunt used to
measure current flowing in or
out of the batteries.
6) Four Conductor Remote Cord: This 25' long
phone cord connects the LINK to the inverter/charger.
This is the smaller of the two cords.
7) Eight Conductor Data Cord: This 25' long cord
connects the Monitor Terminal Board to the Ideal
Regulator Output Module. This is the larger of the
two cords.
Our Customer Service Manager says, "Be a genius—ensure a
successful installation by following our wire-by-wire instructions
and please do the two progress checks and the final startup test."
Be sure the battery shunt is installed before proceeding.
MONITOR BOARD INSTALLATION & WIRING
MOUNTING THE MONITOR TERMINAL BOARD
The Monitor Terminal board should be secured behind or adjacent to the meter. It
should be accessible and easy to see during hookup. The meter comes standard with an
18" ribbon cable.
Wiring is simplified by using our custom multiple conductor twisted pair cable
available from your dealer. See LINK 2000 manual. If you supply your own cable we
recommend 16 AWG. Larger wire is okay but not necessary. Do not use larger than #14
AWG, as it will make terminating the wires difficult. Use twisted pairs where specified. Use
the same color scheme as on the schematic to facilitate troubleshooting if required.
Begin hooking up from the bottom (terminal #1 ) of the terminal strip toward
the top.
9
TERMINAL #1
BLACK WIRE (AGND) is the Analog Ground. It is the reference for all
measurements. It must be connected on the BSHG (Grounded) side of the battery shunt.
The BSHG side of the shunt is the side
opposite of the negative battery terminals. It must
have a good connection to one of the two #10 screws on the top of the battery shunt.
Do not connect anything else to this terminal.
TERMINAL #2 is not used.
TERMINAL #3
WHITE WIRE (LITE) turns on the monitor backlighting. It may be supplied from
a switch that controls other instrument lighting or it may be connected to TERMINAL #4
if you wish the lighting to be on all the time. Set at the default value the backlighting consumes
about 8 mA (0.008 A). If left on all the time it would use less than 0.2 Ah per day.
TERMINAL #4 <<Consider the options for this wire>>
RED WIRE (12 / 24 V) is the +12 V / 24 V power to supply the meter. The wiring
diagram shows two options. The
preferred option is to jumper together TERMINALS
#4 and TERMINAL #5 as shown. Wired this way, the meter cannot accidentally be
de-powered. It has the disadvantage of always consuming a little bit of power from the
#1 Battery. The meter consumes about 28 mA (0.028 A). If left on all the time it would use
about 0.7 Ah per day.
If the system is left on for long periods (long enough to significantly discharge the
battery) with no charging sources available, then you should consider the option shown with
the dotted line. In this case the TERMINAL #4 RED WIRE is
not jumped to the
TERMINAL #5 BLUE WIRE but supplied from the common of the battery switch. (Be
sure to install the 2 A fuse as near the battery switch as possible.) Then, whichever battery
is selected by the battery switch is the battery that supplies the power for the meter.
Caution: With this option, if the battery switch is turned off, the meter is de-powered
and this resets amp hours to zero. Therefore the battery switch should never be turned off
except when leaving the system for a long period of time. When the system is returned to
service you must resynchronize the meter by fully charging the battery.
Another option for the TERMINAL #4 RED WIRE is to install a separate on/off
switch in it before it connects to the terminal board. Just remember to turn off the meter
when leaving the system unattended. (Amp hours will be reset to zero when the unit is
repowered.)
TERMINAL #5 <<See TERMINAL #4 above for options>>
BLUE WIRE (B1V) supplies Battery #1 voltage to the Link 2000-R for sensing.
It should be supplied directly from Battery #1 positive. Be sure to install the 2-amp fuse
shown in the drawing as near the battery as possible.
TERMINAL #6 <<if one battery to be monitored, jumper TERMINAL #5 & #6>>
VIOLET WIRE (B2V) supplies Battery #2 voltage to the Link 2000-R for sensing.
It should be supplied directly from Battery #2 positive. Be sure to install the 2-amp fuse
shown in the drawing.
10
PROGRESS CHECK #1
The wires hooked up so far allow you to check the voltage monitoring functions. Install
the fuse that supplies TERMINAL #4 - Red Wire (+12 V / +24 V) and carefully plug
the ribbon cable into the Monitor Terminal Board, note the connector index key
and be sure the pins are lined up correctly.
From now on you may de-power the meter by unplugging the ribbon cable.
If you remove the fuse that supplies TERMINAL #4 - RED WIRE with the ribbon
cable plugged in, you must be careful when reinstalling it. It must be a deliberate
action. If the power to the meter is turned on and off in less than five-second intervals
it can cause the microprocessor to interrupt its initialization process. De-powering
and re-powering by using the ribbon cable avoids this problem.
Check each of the battery voltages. It is best to have a separate, accurate digital
voltmeter to compare the voltages shown on the Link 2000-R against the actual battery
voltage. They should be within a few hundredths of a volt. If they are not, check your
voltage sense lead fuses and fuse holders.
proceeding. If you have questions, call your dealer or Xantrex Technology Inc.
Unplug the ribbon cable before proceeding, or remove the fuses in the wires to
terminals #4, 5, & 6 before continuing.
<<The next four wires are for the dual battery shunt sense leads.>>
See "Required Reading" in the LINK 2000 installation manual regarding the special
care required in the installation of the shunt and its wiring.
TERMINAL #7 - Jumper to TERMINAL #9 for single bank current measurement.
GREEN WIRE (B1SHG) which is connected to the SMALL SCREW ON THE
GROUND SIDE, OR LOAD SIDE, of the Battery #1 shunt (B1SHG). This wire must be
located exactly as described to ensure accuracy of current measurements. This GREEN
WIRE AND ORANGE WIRE attached to Terminal #8 should be a twisted pair.
Any problems must be resolved before
TERMINAL #8 - Jumper to TERMINAL #10 for single bank current measurement.
ORANGE WIRE (B1SHB) is connected to the SMALL SCREW ON THE
BATTERY SIDE of the battery #1 shunt (B1SHB). This wire should be located exactly
as described to ensure accuracy in current measurements.
NOTE: If only one current input is used, jumper terminals #7 & #9 together
and terminals #8 & #10 together. This hookup will display the same current
information for both the Battery #1 and #2 selection.
TERMINAL #9
BROWN WIRE (B2SHG) is connected to the SMALL SCREW ON THE
GROUNDED, OR LOAD SIDE, of the battery #2 shunt (B2SHG). The TERMINAL #10
YELLOW WIRE and TERMINAL #9 BROWN WIRE should be a twisted pair.
11
TERMINAL #10
YELLOW WIRE (B2SHB), is connected to the SMALL SCREW ON THE
BATTERY SIDE of the Battery #2 shunt (B2SHB). The TERMINAL #10 YELLOW
WIRE and TERMINAL #9 BROWN WIRE should be a twisted pair.
PROGRESS CHECK #2
Now it is time to check the battery current function. Plug the meter's ribbon cable into the
Monitor Terminal Board and/or insert the fuses. Turn off all DC loads and charging sources.
With everything off select Battery #1 or #2 Amps—the LINK 2000-R should read 0.0,
-0.0, or no more than -0.1 A. (The meter uses less than 0.1 A.) If there is a larger current
draw it normally means that not all the DC loads are turned off. There may be an alarm
system, a clock, or other instrumentation that is left on all the time intentionally. That is
okay as long as you find each load and decide that it is an acceptable continuous current
draw. Once your base-line current is known, remember it. If you cannot always turn off loads
and reach the same number of amps you should find out why. Turn on various loads and
make sure there is a minus sign in front of the display which indicates discharge. If the
number has no minus sign and there are no charging sources on, it means that the battery
shunt sense leads are reversed. If you have a problem call your dealer or Xantrex
Technology Inc. The wiring is now complete and the battery monitoring functions of the
meter now are fully operational.
The battery monitoring and inverter/charger functions of the LINK 2000-R may be
operated independently of the alternator regulator functions. Simply unplug the 8 conductor
data cord (described in the next section) between the Monitor Terminal Board and the Ideal
Regulator Output Module to disable the regulator. The alternator will freewheel harmlessly.
IDEAL REGULATOR OUTPUT MODULE WIRING
MOUNTING THE OUTPUT MODULE
The Ideal Regulator Output Module may be located anywhere convenient to the
alternator that is not subject to salt or fresh water spray. The components in this module
have been coated to resist corrosion but are not immune to, nor warranted against, abuse.
This module has on it the FET (field effect transistor) that actually does the work of
supplying power to the alternator field. While the reliability of this module is very high
it also does all of the real work. The system has been designed with on-site repairability
in mind, a spare Output Module or a standby regulator should be considered for longdistance cruising.
The harness that is supplied with this module is a standard alternator harness. It
is keyed so that it cannot be improperly plugged into the module. The colors mentioned
below correspond to the color code of the wiring harness. There is also a 25-foot 8
conductor data cord supplied to interconnect the Monitor Terminal Board and the Ideal
Regulator Output Module. The following discusses each of the wires connected to the
Ideal Regulator Output Module beginning from the left side of the module.
12
FIELD WIRE TERMINAL
BLUE WIRE is connected to the FIELD TERMINAL on the back of the alternator
and supplies alternator field current. The gray insulated plug connector may be plugged
directly into standard small case high output alternators. (NOTE: The white wire that is
stubbed out of the gray plug is for electronic tachometers and has no function related to
alternator regulation.) If the plug will not fit into the alternator it may be cut off and the blue
wire may be terminated with an insulated spade terminal or other appropriate connection
for the alternator field terminal on the alternator. (The RED LED, on the Ideal Regulator
Output Module, labeled CHG indicates field voltage is present on this BLUE WIRE. The
RED LED glows more brightly as the alternator output increases.)
CAUTION: The gray plug will fit into the typical DELCO internally regulated
alternator but the internal regulator must first be disabled. DO NOT attempt to use the
Link 2000-R with an internally regulated alternator without modifying it to use
external regulation! See #4 on page 8.
REG ON TERMINAL
BROWN WIRE supplies the voltage that turns on the Ideal Regulator Output
Module. It should be connected to a normally open oil pressure switch, or some other
switch (such as an ignition switch or relay), that is hot (+12 V / 24 V)
when the engine is
running and off when the engine is off. If the system has a battery isolator, or separate
engine starting battery, the BROWN WIRE should be supplied from a stable 12 V / 24 V
source. This wire must not be connected to the oil pressure sensor for the oil pressure
gauge or to the oil pressure switch for the alarm system. A separate
NORMALLY OPEN
oil pressure switch should be used. When this wire is energized the GREEN LED labeled
ON is lit.
The GREEN LED must be OFF when the engine is off! If the regulator is left
continuously ON it may destroy the Ideal Regulator Output Module, damage the
alternator, discharge the battery, and cause system failure.
+12 V/24 V TERMINAL
RED WIRE is the +12 V / 24 V supply. It is shown connected to the alternator
side of the alternator shunt (ASHA). Connecting it here ensures a stable voltage with little
voltage drop to supply the alternator field power. The 10-amp fuse shown should be
installed to protect the wiring.
If an isolator is in the system, the +12 V / 24 V (Red wire) must connect to the
battery side of the isolator.
GND (GROUND) TERMINAL
BLACK WIRE wire is power ground. It is connected to the alternator ground.
ASHB TERMINAL (alternator shunt battery side)
GREEN WIRE must be terminated on the small screw on the battery side of
the alternator shunt. This wire must be connected exactly as shown. Since this wire is
at battery voltage it should be protected with a 2-amp fuse
at the shunt as shown;
install the fuse after the wiring is connected. No other wires should be connected here.
13
ASHA TERMINAL (alternator shunt alternator side)
YELLOW WIRE must be terminated on the small screw on the alternator side of
the alternator shunt. This wire should be connected exactly as described to ensure proper
operation. Since this wire is at battery voltage it should be protected with a 2-amp fuse
the shunt as shown; install the fuse after the wiring is connected. No other wires should be
connected here.
FINAL TEST AND ENGINE STARTUP
Do this test with the engine OFF!
If you cannot pass this test do not start the engine!
This is the final checkout. Plug the 8 conductor data cord (the larger of the two
phone cords) into the Monitor Terminal Board and the Regulator Output Module. Check
the battery amps—you should see the same low number as in PROGRESS CHECK #2.
The green ON LED on the Ideal Regulator Output Module must be off.
Now we want to simulate the engine running, so turn on the regulator by turning the
key switch to the ON position, or if normally open oil pressure switch is used, jumper
together its two terminals.
terminal while the engine is off. The GREEN ON LED should be ON. The red Charge Cycle
Status light on the Link 2000-R front panel should also be ON. The RED CHG LED on
the Output Module, which indicates that field voltage is being supplied, should gradually
increase in brightness during the next 30 seconds. Also check the TIME function
which should display "a000" indicating the alternator output current is zero.
To verify that current is actually flowing into the alternator field use the LINK
2000-R to check the number of amps flowing from whichever battery has been selected
by the main battery switch. You should see -3 to -5 amps of current flowing. This current
is being supplied to the alternator field, and perhaps, to other instrumentation that is also
turned on with the key switch if you are not using an oil pressure switch.
To verify that it is the alternator field consuming the current, turn off the power
to the REG ON terminal and disconnect the FIELD wire from the alternator field. Repeat
the test. The current should now be about 2 to 4 amps less than it was. This test assures
you that the regulator is supplying the field current.
Another easy way to test if the field is energized is to check the magnetism of the
rotor by touching the end of the alternator shaft with a steel screwdriver. Do it with the
regulator turned on (wait 20 seconds for ramp-up cycle) and with it turned off—there
should be a noticeable difference. If you cannot pass this test see the troubleshooting
flow chart. If you still need help, call your dealer or Xantrex Technology Inc.
For this test only we want to supply voltage to the REG ON
at
14
Neither the GREEN or the RED LED should be ON when the engine
is off! If the RED LED is ON, and the green LED (labeled "ON") is OFF, it is an
indication that the FET is shorted or the field is connected to some other source.
DO NOT OPERATE THE SYSTEM UNTIL THIS IS RESOLVED!
It is now time to start up the engine and see how everything works. For this test
make sure the battery charger or any other charging sources are turned off.
Partially discharge the batteries (remove at least 20% of the capacity—it may take a few
hours at a relativity high discharge rate). Start the engine and watch the battery voltage to
see that it raises to and levels off at about 14.4 (28.8) volts in the Acceptance Cycle. With
the default values, when the battery current falls to about 4 amps (2% of the battery capacity)
the regulator will shift into the Float Cycle and maintain the batteries at the Float voltage.
Also check the alternator current by pressing the TIME button and using a milliVolt meter
to measure the voltage drop across the alternator shunt and comparing it to the reading on
the LINK 2000-R. The milliVolt reading multiplied by ten should about equal the LINK
2000-R alternator current reading. The alternator current measurement is inherently less
accurate than the battery current measurement—you may see up to
+ 3 amps error.
STANDBY REGULATORS
Part of our power system design philosophy is to consider spares and backup
systems before they are needed. We have designed the Ideal Regulator with this in
mind. The Ideal Regulator Output Module wiring harness is compatible with standard P-
Field external regulators. Simply carry a spare regulator that is plug compatible and
just unplug the Output Module and plug in your standby regulator. You may use a simple,
adjustable, constant voltage regulator or we would suggest that you consider the Xantrex
Incharge Regulator, which provides three-stage charging, plug compatibility, and is fully
adjustable.
Install and test your standby regulator or any other spares you might carry
before cruising!
