Using the BUILT-IN Alternator Tester

This battery charger has a built-in alternator tester that displays either an accurate alternator voltage or an estimate of the alternator’s relative output compared to normal alternators. The Alternator % values displayed should be taken as general reference, not precise diagnosis. The alternator tester functions the same as the battery tester (see previous section of this manual for details) with a few differences.

TESTING SEQUENCE

There are three basic steps required to use the 7000A as an alternator tester.

1.Connect the charger battery clamps to the battery or charging system. Be sure to follow all of the precautions listed under “OPERATING INSTRUC- TIONS”.

2.Connect the charger power cord to a 120 VAC outlet. Again, be sure to follow all of the precautions listed under “OPERATING INSTRUC- TIONS”.

3.Start the vehicle and turn on the vehicle’s headlights. Read the voltage on the digital LED or press the

display mode button to set the tester to “Alternator %” and read the alternator percent.

TESTER STATUS LEDs

When the 7000A is operating as an alternator tester, the status LEDs light under the following conditions.

•The CHARGED (green) LED will light if the output of the charging system is at the normally desired level.

•The CHARGING (yellow) LED does not light in the alternator test mode.

•The CHECK (red) LED lights if the voltage is much higher or lower than normally desired.

•When the tester display mode is set to voltage, none of the status LEDs light (it could be testing a battery or an alternator).

ALTERNATOR TESTING NOTES

•The alternator percent display can range from 0 to 199.

•The display mode cannot be set to “Alternator %” during charging.

USING YOUR ENGINE STARTER

OVERVIEW

The 7000A has an engine start function that can be used to jump start your vehicle if the battery is low by providing 70 amps of current to assist engine cranking.

STARTING SEQUENCE

There are a few basic steps involved when using the engine start function.

1.Connect the charger battery clamps to the battery or charging system. Be sure to follow all of the precautions listed under “OPERATING INSTRUC- TIONS”.

2.Connect the charger power cord to a 120 VAC outlet. Again, be sure to follow all of the precautions listed

under “OPERATING INSTRUC- TIONS”.

3.Press the CHARGE RATE button until the 70A START indicator is lit.

4.Crank the engine until it starts or 8 seconds passes.

5.If the engine did not start, wait for the charger to cool then repeat step 4.

During the starting sequence listed above, the charger is set to one of three states.

1.Wait for cranking - The charger waits until the engine is actually being cranked before delivering 70 amps for engine start. The charger delivers charge at a rate of 20 amps
