NOTE: Prior to running this test, turn the headlamps on for 10-15 seconds to remove any surface charge from the battery. Then, wait until the voltage stabilizes before performing the Generator Base Voltage Test. The battery should be at the recommended state of charge.

1. With the ignition OFF and no electrical loads on, connect the ARBST Voltmeter Negative Lead to the battery ground cable clamp.
2. Connect the positive lead of the ARBST to the battery to starter relay cable clamp.
3. Press the MULTIMETER button.
4. Read and record the battery voltage shown on the display. This is called base voltage and will be used in later tests.
