2 I
Checking method
LRemedies
I
Stator DC coil
1.Disconnection
2.Short circuit
I
Measure the resistance value between the terminals with a circuit tester (Measure at the section where diodes are connected)
In case of OQbl ...
Disconnection
In case of Oil ...
Short circuit
rReplace the stator
I
Diode stack
The diode is defective
I
Confirm continuity between the terminals with a circuit tester
Refer to
Replace the diode stack
I
Lead line
Disconnection of the lead line
Measure continuity with a circuit tester
In case of 00 51,the lead line is defective.
Replace the lead line
AVR
AVR failure
Measure resistance value between the terminals with a circuit tester (Measure with a 4P coupler)
If the resistance is different from the standard, replace the AVR
rpm of the engine increases too much (Frequency is too
Measure rpm at the rated load
50Hz: 3000+30rpm
60Hz: 3600”30rpm
Regulate rpm
