a - Voltage regulator/rectifier
b - Stator
c - Fuse (20 amps)
d - Starter solenoid
e - To starter terminal
f - To battery
NOTE: Readings listed are taken at 20 °C (68 °F) with a digital ohmmeter. Due to the number of different manufacturers of
meters available and temperature variance, test results may vary.
NOTE: It is not necessary to remove the stator for testing.
Battery Charge Windings
1. Disconnect the voltage regulator/rectifier from the stator connector, if equipped.
2. Test the three stator battery charge windings for continuity.
DMT 2004 Digital Multimeter
NOTE: The stator is not polarity sensitive when checking ohm resistant values.
