whether the flywheel is out of round, or if the crankshaft
is bent.
If the resistance test, air gap test, and flywheel
inspection all test good, remove the flywheel and
verify the keyway is in good working order. If the
keyway is intact and problems persist, thoroughly
inspect the relevant wiring connections as a electrical
component or connection may persist.
