Alternator Testing Procedure
Alternator Testing:
Check all wiring for burnt or loose
electrical connections. Repair as needed.
Check all grounds and electrical
connections to confirm they are clean
and tight.
A. Alternator ground to chassis frame.
B. Motor block ground to chassis frame.
C. Chassis battery ground to chassis
frame.
D. Alternator positive output to isolator
relay terminal.
Inspect
the alternator for damage.
Check belt, pulley and fan for wear.
Replace as needed.
DO NOT
disconnect the battery, or
battery wire, from the alternator with the
engine running as this can damage the
alternator or regulator.
The pulley for the alternator should be
torqued to 80 ft. lbs.
Chassis battery voltage with the engine
OFF
should range from 12.2 to 12.7 Volt
DC.
Chassis battery voltage with the engine
at idle should range 13.5 to 14.2 Volts
DC.
The output of the alternator range is 13.6
to 15.4 Volts DC. Connect a volt meter
to the (B+) terminal of the alternator and
chassis ground. Idle the engine up to
1200 RPM.
Connect a clamp-on amp-meter, if
available, to the positive battery cable to
verify the battery state/rate of charge.
CAUTION
The alternator is not a battery charger.
The alternator is designed to maintain
proper electrical system voltage. A
battery with a low state of charge, or a
dead battery, may overheat and damage
the alternator.
