2. Turn off all electrical equipment/loads.
CAUTION
If voltage climbs above 33 or more volts,
shut off engine. Alternator could be
damaged.
3. Adjust rheostat to maximum resistance.
4. Connect diagnostic test harness leads 1 and 4 together.
5. Start engine and run at 800 rpm and lower resistance.
6. Does voltage rise above battery voltage (test harness
lead 3 to ground) to approximately 28 volts?
1. Remove alternator test kit (page 3-64.1).
2. Replace voltage regulator (200 amp generator)
(page 9-40).
3. Repeat charging system operational check
(page 3-64.4).
