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.
