Over charging alternator

[ronmarabito2002]

Jim:

The regulator might just give up on its own, but I'm convinced
something is doing it. I looked at the charging system diagram and
see that other than a loose connection to the sensing line, it could
be a faulty ignition switch, since that is the source of the power.

I will be in Hondo, TX in a few days where Jack Pearce and I will
troubleshoot better. He is an electrical engineer. I'll spend a
couple nights there and we'll do something, even if it's wrong.

When that's done, I'll post on the forum with what we found or
didn't find and how we are dealing with the problem.

P.S. I really appreciate all the reponses from forum members.

problem with my front alternator. I think that the regulator must burn
out intermittent short or something. I was getting a high charge rate
and high aperage also. I replaced both alternators as the rear one was
shot, I have driven probally 2500 miles. havn't had a problem since.
The pulleys on my alternators are odd so don't just give them up when
replacing. We had to look around to find an extra one for my back up
alternator. The rear on in my coach is eaiser to replace than the
front one. I don't have a hole in the floor but do have an opening in
front of the engine that I stuff someone into, i just must have a rope
tied to a leg so that I pull out when repair is complete
