24 Volt Displaying weird amp readings

My Selene 53 is having an electrical issue. Looking at the breaker panel it shows the amp meter bouncing from a plus 15 amps or so to a fluctuating minus. -136.6 is an example. Thoughts.Click image for larger version

-136 amps at 24 volts is a very large load. Bigger than a windlass. So as long as there is nothing like that running, then its an instrument problem.
What does it read with all loads shut off and battery charger off?
Do you know if the meter uses a shunt or a coil?
Trace the leads from the meter. Check for loose connections.

What does it read with all loads shut off and battery charger off? The same to a point. It does go up or down quite a bit. Sometimes it just reads normal.
Do you know if the meter uses a shunt or a coil? I donít know but can easily check.
Trace the leads from the meter. Check for loose connections. Will do

Yes, I have. Their are a total of 3 and all are switched off. I have also turned off the mains with the same results showing on the display. Right now we are connected to shore power but it also comes and goes with genset running and cruising.
