Coach Batts overcharging

[freewill2008]

Gary - That is exactly what I would think, but I have a bum shunt that gives bad
readings at the meter and does not pass current reliably. Hard to visually
inspect this one and I have not removed it to find out. Possibly there has been
physical damage at one of the end terminals. For now it is bypassed.

Agree 300% about the meter!

wire crimps, and hardware are more likely problems. If you need to measure DC
in a line or branch, get one of these less than $100 DC clamp on ammeters.Â
They tell you the current and the direction of flow. Don't leave home without
one.

reading. The ammeter uses a shunt which could have failed. That might lead to
a faulty voltage reading as well.

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.
