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.
