Battery Base Voltage Test

NOTE: Prior to running this test, turn the headlamps on for 10-15 seconds to remove any surface charge from the battery. Wait until the voltage stabilizes before performing the base voltage test.

1. With the ignition off and no electrical loads switched on, connect the negative (-) lead of 73 Digital Multimeter to the battery ground cable clamp.
2. Connect the positive (+) lead of 73 Digital Multimeter to the battery to starter relay cable clamp.
3. Read and record the battery voltage shown on 73 Digital Multimeter. This is called base voltage and will be used in later tests.
