Electrical System
Electrical System Quick Checks
Battery Test (Open Circuit Test)
Use a digital multimeter to measure the battery voltage.
Set the multimeter to the DC v olts setting. The battery
should be at a temperature of 60
o
to 100
o
F(16
o
to 38
o
C). The ignition switch should be in the OFF position and
all accessories turned off. Connect the positive (+) multi-
meter lead to the positive battery post and the negative
(--) multimeter lead to the negative battery post. 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).
Voltage Measured
Battery Charge Level
12.68 volts Fully charged (100%)
12.45 volts 75% charged
12.24 volts 50% charged
12.06 volts 25% charged
11.89 volts 0% charged
Charging System Test
This is a simple test used to determine if a charging sys-
tem is functioning. It will tell you if the charging system
has an output, but not its capacity.
Use a digital multimeter set to D C volts. Connect the
positive (+) multimeter lead to the positive battery post
and the negative (--) multimeter lead to the negative bat-
tery post. Keep the test leads connected to the battery
posts and record the battery voltage.
NOTE: Upon starting the engine, the battery voltage
will drop and then should increase once the engine is
running.
NOTE: Depending upon the c ondition of the battery
charge and battery temperature, the battery voltage will
increase at different rates as the battery charges.
Start the engine and run at high idle (3450 RPM). Allow
the battery to charge for at least 3 minutes. 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.
An example of a charging system that is functioning:
At least 0.50 volt over initial battery voltage.
Initial Battery Voltage = 12.30 v
Battery Voltage after 3 Minute Charge = 12.85 v
Difference = +0.55 v
