Meter registering a negative voltage

The meter above the magnum Control is registering a negative number. It's been that way since we've owned the coach. We just recently put in new house batteries, it still registers a negative number.

What is the meter above the Magnum panel?

All 12v meters will read negative when connections are reversed:  Meter positive to battery negative, etc.  Reading is accurate, just don't pay attention to negative sign.  Or swap wires.

Could also be "cumulative/total amps" and that feature needs to be reset. A negative number on that means more discharge than charging.

Again, depends on WHAT is reading a negative number.
