10 11

The fault icon will flash; and the alternator icon, “ALT” and the gage without the pointer will light solid.

4. Press the alternator check button again to stop the test.

Notes: All buttons except the alternator check button are disabled in alternator check mode.

The unit may detect that the alternator is out of typical voltage range 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.

This check may not be accurate for every make, manufacturer and model of vehicle. Check only 12 volt systems.

When disconnecting the charger, disconnect AC cord, remove clamp from vehicle chassis, and then remove clamp from battery terminal.

Reconditioning the Battery

Periodic reconditioning is recommended to maintain a battery’s optimum performance. Battery recondition sends a series of electrical

pulses to break up the crystalline form of lead sulfate and turn these chemicals into useful battery electrolytes. The process will stop

automatically after 24 hours. To stop the process sooner, press the battery recondition button a second time. More than 24 hours may be

needed to restore performance on some batteries. If so, repeat the process.

1. Set up the battery charger and connect to the battery following steps 1 through 2 in the “Charging the Battery” section.

2. Press the battery recondition button. The LCD screen will display the following:

The battery recondition indicator, the clamp icons, the battery icon and the gage without the pointer will light solid, the bars on the

battery icon will change from solid to empty (top to bottom) repeatedly and the battery recondition icons will flash.

3. To stop the reconditioning process, press the battery recondition button again. Pressing any other button during this process will have

no effect.

Important: If 5 cycles of reconditioning does not improve battery performance, discontinue and recycle the battery. The battery charger

will go into charging mode after 24 hours automatically.

When disconnecting charger, disconnect AC cord, remove clamp from vehicle chassis, and then remove clamp from battery terminal.

Using the Engine Start Function

1. Set up the battery charger and connect to the battery following steps 1 through 2 in the “Charging the Battery” section.

2. Press the engine start button. The LCD screen will display the following*:

The digital display shows the countdown.* The battery charge gauge will indicate the battery’s current charge status. The engine

start icon, clamp icons and battery icon light solid, and the bars on the battery icon will change from empty to solid (bottom to top)

repeatedly and the arrow icons will gradually and repeatedly move downward to the battery icon.

*The countdown will commence from “90” to “00”.

3. When “00” is reached, a beep will sound, engine start icon ( ) will begin flashing. The vehicle is ready to start.

4. Crank the engine using manufacturer’s guidelines, typically in 3 to 5 second bursts. The digital display shows “5 sec.” indicating a

5-second countdown.

5. After cranking, the unit will automatically adjust the charging current to 2A for 5 minutes and then revert to charging mode. To stop

charging, press the charge button.

Important: The function requires a resting/cooling period between attempts. Wait 4 to 5 minutes before a second attempt at starting the

engine, if needed.

When disconnecting charger, disconnect AC cord, remove clamp from vehicle chassis, and then remove clamp from battery terminal.

TROUBLESHOOTING

Unit Not Charging

• Make sure all connections are secure.

• Check that the charger is properly connected to a live 120 volt AC outlet.

• If the battery to be charged has fallen below 2 volts, the battery cannot be recharged with these chargers.

.Using the Alternator Check Function

Set up the battery charger and connect to the battery following steps 1 through 2 in the “Charging the Battery” section.

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. Press the alternator check button to start the check. The LCD screen will display the following to indicate the unit is analyzing the

alternator:

“Check” will flash, and the alternator icon and the gage without the pointer will light solid.

2. If the unit detects that the alternator is good, the LCD screen will display the following:

“Good”, the alternator icon and the gage without the pointer will light solid.

3. If the unit detects that the alternator is out of typical voltage range, the LCD screen will display the following:
