TROUBLESHOOTING (GENERATOR)

Practically all breakdowns can be prevented by proper handling and maintenance inspections, but in the event of a

breakdown, use Table 19 shown below for diagnosis of the Generator. If the problem cannot be remedied, consult our

company’s business office or service plant.

Table 19. Generator Troubleshooting

Symptom

Possible Problem

Solution

No Voltage Output

AC Voltmeter defective?

Check output voltage using a voltmeter.

Is wiring connection loose?

Check wiring and repair.

Is AVR defective?

Replace if necessary.

Defective Rotating Rectifier?

Check and replace.

Defective Exciter Field?

Check for approximately 19 ohms across J & K on CN1

Low Voltage Output

Is engine speed correct?

Place engine speed switch in “High” position.

Is wiring connections loose?

Check wiring and repair.

Defective AVR?

Replace if necessary.

High Voltage Output

Is wiring connections loose?

Check wiring and repair.

Defective AVR?

Replace if necessary.

Circuit Breaker Tripped

Short Circuit in load?

Check load and repair.

Over current?

Confirm load requirements and reduce.

Defective circuit breaker?

Check and replace.

Over current Relay actuated? Confirm load requirement and replace.
