(1)

Terminal Voltage for Each Part During Normal Periods (No-load Periods)

(2) Stator Coil

Output Terminal
1. With the NFB in the ON position, measure the voltage in each
phase and each line.
2. If the factory specification is not indicated, inspect the output
circuit or the wiring harness. (Refer to wiring diagram.)
Output voltage Factory spec.
Main Coil Winding
1. Test for continuity between coil leads with a miliohm meter.
Many kind of wiring have been arranged in the stator depending
on the voltage variation.
2. If the resistance is not as specified, replace the stator coil or
contact service station.
Resistance Factory spec.
* Measurement is not possible with a regular tester.
Detecting Coil
1. Measure the coil resistance between each auxiliary winding.
2. If the factory specification is not indicated, replace the stator coil
or contact service station.
Resistance Factory spec.
Grounding of Stator Coil
1. Measure the insulation resistance between each stator winding
and lamination with a megaohm meter.
2. Reading should be more than 1 M 
3. If continuous, replace the stator coil or contact service station.
