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, SW1 and Relay ON (SW2 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 a light instead of a voltmeter.
