Voltage Test

Example of Voltage Test:

Voltage Test:

1 Voltmeter
2 Power distribution box (fuse)
3 Switch for reversing light (OFF)
4 Rear light
A Measured value: U-Batt
B Measured value: No voltage

Measuring instrument: Voltmeter

Test Procedure:

To take a voltage measurement, connect the negative lead of the voltmeter to the vehicle ground (negative terminal of the battery or good ground connection). Then connect the positive lead of the voltmeter to the point you want to test. The voltmeter will then indicate a voltage value.
