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

Set the multimeter to the DC volts setting. The battery
should be at a temperature of 60o to 100o F. The ignition
keyshouldbeoffandallaccessoriesturnedoff.Connect
the positive (+) meter lead to the positive battery post
and the negative (--) meter lead the the negative battery
post.

Charging System Test
This is a simple test used to determine if a charging sys-
temis functioning. It will tell you if acharging system has
an output, but not its capacity.
Start the engine and run at high idle. Allow the battery
to charge for at least three (3) minutes. Record the bat-
tery voltage.
UseamultimetersettotheDCvoltssetting.Connectthe
positive (+) meter lead to the positive battery post and
the negative (--) meter lead to the negative battery post.
Leave the test leads connected and record the battery
voltage.
An example of a charging system that is functioning:
At least 0.50 volt over initial battery voltage.
Initial Battery Voltage
Battery Voltage after 3 Minute Charge
Difference
= 12.30 v
= 12.85 v
= +0.55 v
NOTE: Upon starting the engine, the battery voltage
will drop and then should increase once the engine is
running.
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.
