Voltage Measurement

Voltage Measurement:

1 Using a voltmeter, connect the negative lead to a good ground point or negative battery terminal and the positive lead to the connector or component terminal.
2 Contact the positive probe of the voltmeter on connector (A).
The voltmeter will indicate a voltage.
3 Shift the positive probe to connector (B). The voltmeter will indicate no voltage.
With test set-up held as it is, turn switch ON. The voltmeter will indicate a voltage and, at the same time, the light will come on.
4 The circuit is in good order. It a problem such as a lamp failing to light occurs, use the procedures outlined above to track down the malfunction.
