FAULT

PROBABLE CAUSE

 

REMEDY

 

 

 

 

No AC output.

 

8.

Check insulation resistance between the

 

 

 

stator core and each stator leads. Check

 

 

 

using a megger tester. Replace the stator if it

 

 

 

fails the megger test.

 

 

 

 

 

Rotor fault.

1.

Check rotor.

 

 

2.

Remove generator rear cover and stator

 

 

 

(refer to COMPONENT REPLACEMENT for

 

 

 

procedures).

 

 

3.

Using a multimeter, measure field coil

 

 

 

resistance. Measure resistance at the

 

 

 

soldered terminals of the rotor and the core.

 

 

NOTE: Because a diode is soldered to the coil

 

 

ends at the terminals, resistance may be

 

 

measured only when the multimeter probes touch

 

 

the terminals in one combination of polarity.

 

 

Therefore, if no resistance reading appears, try

 

 

checking in reverse polarity.

 

 

4.

Using a megger tester, check insulation

 

 

 

resistance between the soldered terminal and

 

 

 

the stator core.

 

 

5.

Replace rotor if it does not meet the

 

 

 

resistance values in Table 6.

 

 

 

 

AC voltage too high

Engine speed too high or

2.

Operate the generator with no load applied

 

 

 

 

 

on the generator.

 

 

3.

If the speed is too high or too low, adjust

 

 

 

throttle adjustment screw to set engine speed

 

 

 

as specified in Table 6.
