Voltage Check

Voltage Check:

a. Establish condition 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 a light instead of a voltmeter.
