Default Re: Voltage Spikes

Had a similar problem last year with 2 different alternators. ................ After talking
to John Andreka at East Coast Auto Electric , I traced the problem to a ground jumper wire that had high resistance due to corrosion between the attaching bolt and the aluminum head it was attached to.
Fixed the ground and have not had the problem reoccur.
