Coach Batts overcharging

[freewill2008]

Fred - In that case the instruments could be giving you a faulty reading. The
ammeter uses a shunt which could have failed. That might lead to a faulty
voltage reading as well.

Another possiblity is a relay (solenoid) failure that is causing the charging
system to max out, although I would expect that to show up on both house and
engine systems. This leads to the controls mentioned in the other reply, so that
is a good place to start. In any case check the shunt on that house ammeter so
you know the reading is accurate.

Good luck with it.
