A description of the main areas of each circuit inspection is shown in the table above.
Voltage Check
VOLTAGE CHECK
a. Establish conditions in which voltage is present at the check point.
Example:
[A] - Ignition SW on
[B] - Ignition SW and SW 1 on
[C] - Ignition SW, SW 1 and Relay on (SW 2 off)
b. 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.
This check can be done with a test light instead of a voltmeter.
