(described at the end of this section). Then disconnect the AC cord and clamps, observing the “Important Safety
Instructions” at the front of this manual.

Reconditioning the Battery

Whenever a lead-acid battery begins to discharge, lead sulfate, an insulator, begins to build up on the battery’s internal plates.
This reduces the ability of the battery to hold a full charge. When that battery has an immediate charge, most of the lead sulfate
is dissolved and the plates are free of this insulation. If a battery remains in a discharged condition over a longer period of time,
the lead sulfate changes to a hard crystalline form, making a full charge difficult to achieve. Reconditioning may “save” a
sulfated battery.

Battery Recondition Mode should only be used with 10 Amp Hour (Ah) or larger capacity lead-acid batteries. Charge the battery
to be treated for 20 minutes (as outlined in the “Charging the Battery” section), before using Recondition Mode. Observe the
Digital Display for any Fault Condition messages. This initial charge will check the battery for shorted cells, open cells or battery
too low to accept a charge, and to ensure the battery can take a charge.

CAUTION: Remove or disconnect the vehicle’s battery when reconditioning.

1. When the WELCOME message displays on the LCD, press the Battery Recond. button on the Control Panel to start the
process.

2. RECONDITIONING BATTERY shows on the LCD display.

3. The process takes 24 hours and stops automatically. The display shows “RECONDITIONING CYCLE COMPLETED” when the
process is complete.

4. To turn off the unit, press the Recondition button again. STANDBY will display on the LCD and the unit will be in Standby
Mode (described at the end of this section). Then disconnect the AC cord and clamps, observing the “Important Safety
Instructions” at the front of this manual.

Alternator Check

Part 1

No Load (Turn OFF all vehicle’s accessories): The battery must be fully charged before testing the alternator. Run the engine

long enough to achieve normal idle speed and verify there is a no-load voltage.

1. Set up the unit as described in the “Setting Up the Unit” section.

2. When the WELCOME message displays on the LCD, press the Alternator Check button on the Control Panel to start the
process. The LCD shows ALTERNATOR CHECK.

3. Once the unit has finished checking, the LCD will display either ALTERNATOR VOLTAGE GOOD or ALTERNATOR VOLTAGE BAD.

4. Press Alternator Check again to stop the test.

Part 2

Under Load (Accessories ON): Next, load the alternator by turning on as many accessories as possible (except for A/C and

DEFROST) and repeat the above four steps.
After completing both alternator checks, turn the unit off by pressing the Alternator Check button again. STANDBY will display

on the LCD and the unit will be in Standby Mode (described at the end of this section). Then disconnect the AC cord and
clamps, observing the “Important Safety Instructions” at the front of this manual.

If the first alternator check indicates a good alternator and the second indicates the alternator is not good, the problem could
stem from: loose fan belts, an intermittent diode failure or possibly bad connections between the battery and alternator and/or
ground.

ALTERNATOR VOLTAGE BAD may display because someone has added a number of accessory loads on the charging system,
thereby increasing current demand from the alternator. MAKE SURE THAT THE ALTERNATOR IS RATED TO SUPPORT THE
APPLICATION.
Note: This check may not be accurate for every make, manufacturer and model of vehicle.

Check only 12 volt systems.
