Testing For Voltage

Voltage Check:

1. Connect one lead of a test light to a known good ground. When using a Digital Voltmeter (DVM), be sure the voltmeter's negative lead is connected to ground.
2. Connect the other lead of the test light or voltmeter to a selected test point (connector or terminal).
3. If the test light illuminates, there is voltage present. When using a DVM, note the voltage reading.
