MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
Step 2.
Close the circuit breaker; if the circuit breaker will not stay closed, it is defective.
Refer to field maintenance for replacement of the circuit breaker.
3.
GENERATOR VOLTAGE TOO HIGH
Step 1.
Test the voltage adjusting rheostat (variable resistor) by referring to para. 4-46c. If test renders the
rheostat defective, replace. Refer to figure 461 or 4-62 to remove rheostat from the applicable
model generator set. If rheostat is not the cause of the malfunction go on to step 2.
Step 2.
Inspect the voltage regulator for loose wires, corroded wiring, metal to metal contact, incorrect
wiring or other damage.
Determine if the voltage regulator is defective by performing voltage regulator on-
equipment test as described in paragraph 4-42b.
4.
GENERATOR VOLTAGE FLUCTUATES
Step 1.
Check for fluctuating or faulty engine speed by referring to the engine maintenance manual, TM 5-
2805- 259-14 or TO 38G2-89-41.
Make the adjustments and replacement of defective parts as delineated in TM 5-2805-259-
14, or TO 8G-89-41. If engine speed is not fluctuating, go on to step 2.
Step 2.
Test the voltage adjusting rheostat (variable resistor) by referring to para. 4-46c. If test renders the
rheostat defective, replace it. Refer to figure 4-61 or 4-62 to remove rheostat from the applicable
model generator set. If rheostat is not the cause of the malfunction, go on to step 3.
Step 3.
Inspect the voltage regulator for loose wires, corroded wiring, metal to metal contact, incorrect
wiring or other damage.
Determine if the voltage regulator is defective by performing voltage regulator on-
equipment test as described in paragraph 4-42b.
