Over charging alternator

[ronmarabito2002]

I lost my alternators back in October from an over charge rate.
Re-built just one of the units and it charged correctly until
yesterday (1400 miles since re-build) and went to 16 volts and 100
amps output again. The other alternator was not connected and has not
been re-built. I found out that this can be caused by loosing the
circuit,(Open circuit) such as, losing the connection of the battery
cable on the alternator. Anyone know of a similar case that would aid
me in troubleshooting this problem.

Since the alternator is the front unit under the bedroom floor on
my 92WB40, I do not intend to remove the floor till I get home. I've
disconnected the alternator and now running my generator and charging
from the battery chargers. Hate to put that many hours on the genset,
but don't want to waste time during this trip trying to find what's
causing this problem.

Give me any thoughts you might have.

Ron , Wander if it had something to do with the solenoid that
disconnect and reconnect the alts to both banks. maybe there is a way
to hard wire it up to the start bat bank, and not run it to the dis
connect relay???(or repair the relay??). When My 94 starts up the
alts charge both banks and a light on the dash comes on. I am only
guessing that the alt outputs run to a relay/Solenoid before the
battery. I dont know if it is necessary to protect the alts from A/C
Chargers (heart). I will look for a BB charging sym if it will help.

On my 92, alternators show charge on the Coach only unless the switch
is tying the two banks of batteries together. Can't remember for sure
if both showed charge regardless of switch position. Seems as though
they should. Might be something to investigate further. Thanks.

Ron,

I have a 88 WLWB XXV 8V92 with two alternators. I had a similar 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

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.
