Remove stator plug, start engine and measure AC voltage across pins. Is stator output 16 to 20 volts per 1000 RPMs?
YES>Replace voltage regulator. Retest.
No>With engine OFF measure resistance across stator pins.Is resistance more
than 0.5 Ohms?
Yes>Replace stator/rotor. Retest.
No>With engine OFF, measure resistance from stator pin to engine ground. Good?
Yes>Replace stator/rotor. Retest
No>Reconnect the two-pin stator plug and retest stator/rotor.If low voltage condition still exists, replace stator/rotor. Retest.
