Introduction
Power Probe IV
Thank you for purchasing the Power
Probe IV Diagnostic Electronic Circuit and
Component tester. The Power Probe IV is
the next generation of Power Probe Circuit
Testers. Now loaded with powerful multimeter functions, advanced diagnostic test
modes, an easy to read color LCD display
and a new rugged water and dust resistant
housing, the Power Probe IV is designed to
give you years of trouble free testing, even
in the most demanding work environments.
The unique confi guration of Power Probe
testers gives them many advantages over
using conventional test lights or multimeters
for circuit testing.
(1) Since the Power Probe IV is connected to
the battery, you can apply battery power or
battery ground directly to the tip of the tool.
You can energize and activate components
to verify their correct operation. This is real
dynamic component testing and the only
true way to test an active component.
(2) The Power Probe IV is always connected
to the vehicle’s battery, so the tool maintains
a permanent connection to the source
power and ground voltage. Circuit voltage
checks are quickly performed with just a
single probe connection, unlike using two
meter leads.
(3)Using the PPIV, all your voltage checks
are referenced back to the source battery
and account for every connection and
possible voltage drop between the source
and the probe tip.
(4) Automatic Voltage Drop Indication
When probing a circuit, if the voltage
measured at the tip is 0.5 volts lower (or
more) than the source battery voltage, the
red LED will not Illuminate and no speaker
tone will sound. This will instantly alert you
that there is a voltage drop that may need
to be investigated or repaired.

The Power Probe IV is designed
to connect to and is powered by
12 to 24 VDC electrical systems.
It comes supplied with a 23 ft.,
heavy duty power cable and a
Y-connector with 2 battery clips.
Connecting to the Vehicle’s Battery
(Voltage Source)
Connect the red clip to the positive
terminal of the vehicle’s battery
source and the black clip to the
negative or ground terminal. The
Power Probe IV start-up tone will
sound.
Auxiliary Ground Lead
The auxiliary ground lead
provides ground to circuits and
components that are not already
connected to ground. It also
serves as the negative lead for
resistance testing. To test the
auxiliary ground lead, contact
the probe tip and the auxiliary
ground lead together. The Green
LED should illuminate. This shows
that the auxiliary ground lead is
working properly. If the green
LED does not illuminate, check
the replaceable 20 amp fuse in
the auxiliary ground lead. The
fuse is for protection in the event
the ground lead inadvertantly
contacts the battery positive.

Power Probe IV
Testing and Measuring Operations
DC Voltage Measurement in VDC Mode
In this mode, you will supply battery power or battery
ground to the tip when pressing the rocker switch
VDC - VDC mode is for testing DC (direct
current) voltages. Voltage testing is as easy as
contacting the probe tip to a circuit and reading
the display. The Power Probe IV will display the
probe tip voltage in the center display.
The Power Probe IV automatically enters VDC
Mode when fi rst connected to the vehicle’s battery,
or to a 12-24 volt power supply. VDC Mode is
the only mode that the Power Probe IV can supply
battery power or ground by pressing the rocker
switch.
If the Probe tip voltage is within 0.5 volts of the
source battery voltage and the circuit resistance
is less than 10 Ohms, the Red LED will illuminate
and if the speaker is turned on, the speaker will
make a high-tone.
When testing on ground circuits, as long as there
is less than 10 Ohms total circuit resistance from
tip to battery ground, the Green LED will illuminate and the speaker will make a
low-tone.
This greatly simplifi es testing as the Power Probe IV’s Red/Green LEDs and speaker
tones provide a quick indication if there are excessive voltage drops or circuit
resistance. If the LEDs do not illuminate and there is no tone from the speaker, you
know instantly there may be a circuit problem.
Minimum and Maximum (MIN/MAX) voltages are shown on the bottom of the
display. To reset the MIN/MAX, press the left “CLR” button beneath the display.
VDC mode has a very high sampling rate that is good for tests where the tech is
looking for glitches or deviations from the main signal. This is a very sensitive mode
that can capture even the smallest voltage spikes or drop-outs without having to use
a scope.
The Power Probe IV can safely measure up to 200 VDC.

Testing and Measuring Operations
Activating Components in VDC Mode
Activating Electrical Components in VDC Mode is one
of the main features that make the Power Probe IV very
useful when testing. Being able to apply battery power
or ground right to the probe tip gives you the ability to
activate and dynamically test electrical components such
as lights, motors, and solenoids.
You can power up components on the vehicle or on the
bench by utilizing the auxiliary ground lead. This type
of dynamic component testing is the only true method
to verify a components correct operation. Testing a part
with a volt-ohmmeter may tell you if the part is out of
spec, but you never really know if the part is good until
it is operating under power.
Pressing the rocker switch forward supplies battery
power to the probe tip.
Pressing the rocker switch rearward supplies battery
ground to the probe tip.
The power output is circuit breaker protected. If the
component being tested draws too much current, or the
circuit has a shorted condition, the Power Probe IV’s
circuit breaker will trip protecting the tool and the circuit.
When the
circuit breaker is
tripped, the PPIV
display will show
“CIRCUIT BREAKER
RESETTING” and
will automatically
reset itself after a
few seconds.
www.powerprobe.com · 800-655-3585
Pressing the rocker
switch in any other
mode will not apply
power or ground and
the main screen will
display a large red
“X”.

Power Probe IV
Testing and Measuring Operations
Power Feed Testing
FEED TEST - Power Feed Test (PFT) is used to
check resistance on static circuits or voltage
drops on active circuits by simply probing
one connection of the circuit being tested.
PTF measures total circuit resistance from the
source battery accurately whether there is
voltage on the circuit or not, unlike standard
multimeters. With the Aux. Ground lead, PFT
can also be used like a standard ohmmeter.
PFT displays both Battery and Tip voltage
simultaneously for easy voltage drop test.
In this mode, the Power Probe IV display will
show:
- Total circuit Resistance on the
1
center screen.
- Probe Tip Voltage.
2
- Battery Voltage.
3
The battery voltage and the tip voltage are
both displayed along the bottom of the
screen for easy voltage drop testing.
The circuit resistance will be calculated even with voltage applied to the circuit.
To accurately test the power and ground feed resistance, the component must be
removed from the circuit fi rst. Simply unplug any component, relay, or module on the
circuit, contact the probe tip to the circuit and view the circuit resistance.
PFT will display battery voltage (BATT V) from the battery clips in the lower left display
area, probe tip (TIP V) voltage in the lower right display area and will provide total
circuit resistance readings in the main area of the display all in one test.

Testing and Measuring Operations
Power Feed Testing
To test, fi rst disconnect the device or load being operated from the circuit, then
contact the probe tip to the circuit being tested. Disconnecting the component
from the circuit prevents it from affecting and altering the resistance reading.
If the circuit resistance is less than 10 Ohms the Red or Green LED will
illuminate and the speaker will make a corresponding tone if the speaker
is on. Any differences between battery voltage and tip voltage are easily
observed.
PFT can also be used as an ohmmeter on wire or components not connected
to battery power or ground. Simply connect the item being tested between
the probe tip and the auxiliary ground lead and read the resistance reading
in Ohms.
While it is possible to ohm check some components, it should be noted that
PFT is primarily for use on wiring only and should never be connected to a
solid state component such as a module.

Power Probe IV
Testing and Measuring Operations
AC Voltage Measurement (RMS)
AC RMS mode is for measuring AC
(alternating current) voltages and can
be used on any AC voltage or pulsed
waveform signal where an RMS averaged
voltage measurement is required.
Contact the probe tip to the circuit and it
will display an RMS averaged AC voltage
reading in the main display area while also
displaying RMS Min/Max AC voltages on
the bottom line.
Powering up and activating circuits with the
rocker switch can not be performed in this
mode.
Pressing the “CLR” button will reset the
Min/Max readings.
AC RMS Voltage is used in the same
manner as a standard DVOM would be
used to measure the averaged AC voltage
in any circuit that produces AC voltage.
This can be used for, but not limited to, tests
such as checking alternator diode ripple,
abs sensors, crank sensors, etc.
The Power Probe IV can safely measure up
to 200 VAC.
Warning: Do not use the Power Prove IV to test AC line voltage such as 120V wall plug.
This will damage the probe and could cause personal injury. Vehicle use only.
www.powerprobe.com · 800-655-3585
Power Probe IV
Testing and Measuring Operations
AC Voltage Measurement (P to P)
P-P mode can be used on any AC voltage
signal where a Peak to Peak (P-P) voltage
measurement is required.
P-P stands for Peak to Peak AC voltage. Where
AC RMS displays an averaged AC voltage,
P-P does not average the reading but displays
the total voltage difference from the lowest to
highest voltage extreme on an AC signal.
In this mode, the display will be an AC Voltmeter
that shows the Tip Voltage in the center and the
Min/Max voltage readings along the bottom of
the display.
The voltage displayed is the total voltage
potential between the lowest and highest
voltage sensed on the AC signal being
measured.
Page 13
Powering up and activating circuits with the
rocker switch can not be performed in this
mode.
The total Peak to Peak voltage will be shown
in the main display area. The Min voltage will
display lowest absolute voltage on the bottom left of the display and the Max voltage
will display the highest absolute voltage on the bottom right of the display.
For example, if you have an AC signal that alternates from -50V to +50V the Power
Probe IV will display a P-P voltage of 100V, a Min voltage of -50V and a Max
voltage of +50V.
Pressing the “CLR” button will reset the Min/Max values.
This can be a more accurate test for signal circuits such as sensors or data
communication lines where measuring the full range of the AC signal is required.
The Power Probe IV can measure P-P AC voltage from -100V to +200V.

Frequency Measurement
Hz FRQ CTR – Frequency Counter mode
is used for measuring the frequency of an
alternating voltage signal.
Contact the probe tip to the circuit and it
will display the frequency in Hertz (cycles
per second) in the main display area while
also displaying the – Pulse Width and +
Pulse Width in milliseconds on the bottom
line.
The Power Probe IV can measure
frequencies from 1Hz to 9999Hz.
FRQ CTR can be used for tests where
frequency or pulse width are needed such
as MAF sensors, wheel sensors, etc.

Power Probe IV
Advanced Testing Operations
PPECT Mode
PPECT = PPECT Mode is designed
to work with the Power Probe ECT2000 for
locating open circuit conditions in wiring.
When using the ECT2000 to fi nd opens
in wiring, the ECT Transmitter injects a
specialized digital signal that is normally
picked up by the wireless ECT Receiver.
In some situations, such as large wiring
bundles or limited access, pinpointing the
ECT signal and locating the exact point of
the wire failure may be diffi cult when using
the ECT Receiver alone.
When you select the ECT Mode, the Power
Probe IV is now specifi cally tuned to detect
the ECT open circuit signal. The Power
Probe IV is meant to work by direct contact
to the circuit.
Probe and contact the circuit with the ECT
signal on it and the main display will show
“DETECTED” and the Red/Green LEDs will
illuminate, verifying you are the correct
wire. This can greatly aid in detecting opens
in tight wire bundles or confi ned locations.

Fuel Injector Mode
FUEL INJ = Fuel Injector Mode is specifi cally set-up for fast and easy injector circuit
diagnosis. One quick connection to the circuit and the Power Probe IV will display all
the needed fuel injector testing information that would normally require using an labscope.
Below is an example of a typical fuel injector voltage waveform on a lab scope.

ground, or ECM Ground Voltage.
The windings inside of a fuel injector produce a magnetic fi eld when the injector
is energized. Each time an injector is turned off, this magnetic fi eld collapses back
into the injector windings and induces a hi-voltage spike. This voltage spike is the
Inductive Kick Voltage.
3
This is displaying
a single injector
pulse. The vertical
axis represents the
circuit voltage and
the horizontal axis
represents time.
Following the
waveform from left
to right, you can see
the circuit voltage
starts near battery
voltage until the
injector is turned on,
this is the Injector
Supply Voltage.
Then the voltage will
drop to near zero
when the ECM/
PCM switches to
The time between when the injector is turned on to when the injector is turned off is
simply called the Injector On-Time and is usually expressed in milliseconds. The Power
Probe IV displays each of these four data points on one screen giving a complete
picture of the electrical performance of the injector and the entire injector circuit.
The Red/Green LEDs above the LCD display will blink and are sychronized with the
injector signal from the ECM with a corresponding tone from the speaker output. These
audible and visual cues can quickly identify any intermittent loss of signal from the
ECM.

• Select FUEL INJ from the Power Probe
IV’s test menu.
• Back-probe on the negative side of
the injector, either at the injector or
at the PCM.
• These four data points represent the

corresponding waveform points.
(see pg. 16)
• When the engine is running (or
cranking) the Power Probe IV’s red
and green indicator LEDs will blink
to indicate a good signal from the
ECM/PCM.
• The main screen will display
complete injector circuit data for
quick comprehensive injector circuit
diagnoses.

ON- ms = Injector Pulse On-Time (milliseconds) - This is the total amount of
time that the fuel injector is energized and supplying fuel to the cylinder. This can be
compared to scan tool PID data to see if commanded on-time equals actual on-time
2
IND-K V = Inductive Kick Voltage - Normal inductive kicks range between 55
and 90 volts. You should see a similar voltage number from each of injectors on the
engine. Note: The height of the inductive kick is sometimes cut-off by an internal
ECM diode to about 35 to 45 volts. Note: This test does not apply to hi-pressure
injectors used on diesel engines and gasoline direct-injection engines.
3
ECM V = ECM Ground Voltage - The engine computer activates each fuel
injector by completing the ground circuit with an internal transistor switch. When
the fuel injector is energized, the ECM ground voltage should be close to zero volts.
Actual measured ECM ground voltage can vary, and may be closer to 0.5 volts
because of the internal resistance of the switching transistor.
4
INJ V = Injector Supply Voltage - This is the battery power being supplied
through the fuel injector itself. Measured voltage should be close to full battery
voltage. There may be small voltage drops in the circuit, however, anything more
than 0.5 volt loss from the source battery voltage should be investigated.

Advanced Testing Operations
Driver Testing
DRV TST = Driver Test Mode is design
to test the drivers (transistor) inside the
module’s (PCM, BCM, GEM, etc.) control
circuit.
More and more electrical components
on modern vehicles are being turned on
and off by computer modules or Electronic
Control Units (ECUs). Many components,
such as transmission solenoids or fuel
injectors, can be switched directly from
the ECU. Other high current components,
like radiator fans are operated thru relays
which are then controlled by the ECU.
Special transistor circuits, called driver
circuits, are built in to these modules that
can supply the current necessary to power
these different parts.
Driver circuits current carrying capabilities
are limited, and a shorted component that
draws more current than it should can
overload the driver circuit and cause it to
fail.
When testing the control signal to a
component, relay or solenoid, the module
will need to have the voltage present that the component normally would
supply into the module. If the component, relay, or solenoid is unplugged
the module will no longer be able to pull the voltage to ground and may
not energize the circuit. DRV TST provides a safe voltage supply to validate
the circuit or the driver inside the module without the relay or component
installed.
Modern ECUs have circuits that let the ECU know if a component is actually
plugged in, and the driver circuit will not energize the circuit if no component
is there. Also, in order for the computer to detect output faults, like shorts or
opens, the component being driven has to be within a specifi c resistance
range or the computer also will not energize the driver circuit. When the
Power Probe IV is in Driver Test Mode, it will provide the necessary voltage and
pull-up resistance to ensure proper driver testing. (see product specifi cations
pg.19)

Driver Testing
Driver Testing Explained:
Suppose you had a shorted solenoid that was not working. You know the
solenoid will have to be replaced, but you don’t yet know if the driver circuit
was damaged and you may need to also replace the module. You need a
way to safely test the driver circuit without the component connected.
Driver Test Mode will supply a safe, current limited voltage that can be
connected directly to the module driver output.
Connect a bi-directional scan tool to the vehicle and command the circuit
being tested to an “On” state. You should see the PPIV screen respond if the
driver circuit is working.
It is possible to test some driver circuits without a bi-directional scan tool,
however, you will have to know what running conditions will make the circuit
you are testing switch to an “On” state and then re-create those conditions to
energize the circuit.
