Possible Cause
Solution
1.0
The engine is not charging the battery.
1.1
The
regulator/rectifier
is bad.
Check the B+ voltage from the
regulator/rectifier to ground. With
the engine running at normal RPM
the voltage should be 12.5 to 14.5
DC volts. If necessary, replace the
regulator/rectifier.
1.2
The
stator winding
is bad.
Check for AC voltage at the regulator/
rectifier. The stator should be pro-
ducing an AC voltage of around 25 to
40 volts. Check your Owner’s manual
for the exact voltage. If necessary,
replace the stator winding.
