Floating volt and amp guage
I have a 2003 Dutch star diesel pusher. The info station on the passenger side front where the hwh on/off switch is, there are floating meters measuring house battery volts and amps. The volt meter reads between 13 and 13.5 volts. The amp meter has disappeared showing 0 amps. Occasionally, it will float up just enough to show red but then disappears again. Has done this for a month now. I have pulled all 4 house batteries, cleaned them and cables, added a little water, checked them with hydrometer and they all tested good. Local RV shop can't see me for 2 months. Typical.
Anyone out there have any ideas? Thanks much.
