Electrical System Quick Checks
Battery Test (Open Circuit Test)
Use a multimeter to measure the voltage between the
battery terminals.

should be off and all accessories turned off. Connect the
positive (+) meter lead to the positive battery post and
the negative (–) meter lead to the negative battery post.
Measure and record the battery voltage.

NOTE: This test provides a relative condition of the bat-
tery. Load testing of the battery will provide additional
and more accurate information (see Battery Service in
the Service and Repairs section of this chapter).
Charging System Test
This is a simple test used to determine if the charging
system is functioning. It will tell you if the charging sys-
tem has an output, but not its capacity.
NOTE: Depending upon the condition of the battery
charge and battery temperature, the charging system
voltage will increase at different rates as the battery
charges.
Tool required: Digital multimeter set to DC volts.
Start the engine and run at high idle (3400 RPM). Allow
the battery to charge for at least 3 minutes. Record the
battery voltage.
Test instructions: Connect the positive (+) multimeter
lead to the positive battery post and the negative (–)
multimeter lead to the negative battery post. Keep the
test leads connected to the battery posts and record the
battery voltage.
After running the engine for at least 3 minutes, battery
voltage should be at least 0.50 volt higher than initial bat-
tery voltage.
NOTE: Battery voltage must be greater than 5 VDC for
the alternator system to have any output. If battery volt-
age is less than 5 VDC, charge battery before perform-
ing charging system test.
Example of a charging system that is functioning:
At least 0.50 volt over initial battery voltage.
NOTE: Upon starting the engine, the battery voltage
will drop and then should increase once the engine is
running.
