10. TROUBLESHOOTING

10-1 No AC output

*Checking the exciting coil for resistance. (RGV12100) (Refer to 8-6.) If insulation is NG, replace exciting coil with new one.

* Checking the brush and slip ring of rotor for resistance. (Refer to 8-5 and 8-7.)

If insulation is NG, replace brush and slip ring with new one.

* Check stator for winding resistance between terminals. (Refer to 8-4.)

If stator is faulty, replace with new one.
* Checking stator for insulation resistance.	(Refer to 7-3.)
If insulation is NG, replace stator with new one.
* Checking the A.V.R . (RGV12100)	(Refer to 8-8.)
If insulation is NG, replace A.V.R with new one.
* Checking the diode unit and C.T . (RGV13100T)	(Refer to 8-9 and 8-12.)

If insulation is NG, replace diode unit and C.T with new one.

10-2 AC Voltage is too high or too low

*Check engine speed.

Nominal engine speed at no load ; 3,700 to 3,750 rpm

If engine speed is too high or too low, adjust to the rated rpm.

* Check stator for winding resistance and insulation.	(Refer to 8-4 and 7-3.)
* Check rotor for resistance and insulation.	(Refer to 8-5 and 7-3.)
* Checking the idle control unit. (RGV12100)	(Refer to 8-11.)

If insulation is NG, replace idle control unit with new one.

10-3 AC voltage is nominal at no-load, but load cannot be applied.

*Check engine speed.

If engine speed is low, adjust to the rated rpm.

*Check total wattage of appliances connected to generator.

If the generator is overloaded, reduce the load to the rated output of generator.

*Check appliance for trouble.

If the appliance is faulty, replace it.

*Check if engine is overheated.

If generator cooling air inlet and/or outlet is clogged with dirt, grass, chaff or other debris,

remove it.
* Check insulation of generator.	(Refer to 7-3.)
