Help! Bogart Solar Controller Overcharging
I have three 140w panels on the roof with a Bogart SC-2030 charge controller and a Trimetric monitor. Left the camper to go four wheeling and returned to see the batteries (Two group 31 AGM) chargi...

The obvious culprit to a battery temperature sensor reading incorrectly, is the battery temperature sensor itself or its wiring, or where it connects to the solar controller.
Inspect.
The Dang 'tighten stranded wire under screw' type of wire terminals will Always cause issues at some point either from oxidation or with the screws backing off and not being tight enough.
Such terminals might makes things frinedly for the end user with little skill to hook things up themselves, but they are doomed to cause issues. It is only a matter of time.
It does not matter how much care/torque was used in the crushing of that stranded wire under a screw terminal, it will at some point be too loose and the copper will oxidize and introduce resistance, causing more heating, causing more looseness and accelerated oxidation, until failure of the connection.
Tick tick tick.
