Electrical System Quick Check
Battery Test (Open Circuit Test)
Use a multimeter to measure the voltage between the
battery terminals.
Set multimeter to the DC volts setting. The battery
should be at a temperature of 60 to 100
o
F (16 to 38
o
C).
The ignition key should be off and all accessories turned
off. Connect the positive (+) meter lead to the positive
battery post and the negative (−) meter lead the the neg-
ative battery post.
NOTE: This test provides a relative condition of the bat-
tery. Load testing of the battery will provide additional
and more accurate information.
