Yesterday about 50 miles from our destination I saw that the voltage gauge was at zero. I immediately freaked and shut off the lights and fans, thinking the alternator may have taken a dump. Then it came back up to 12v and shortly after went back down. A little bit after that I noticed the engine and trans coolant levels appeared lower than usual. Well, they were static, not moving, as I normally watch the coolant temp closely. So a few miles down the road I’m watching the Magnum ID. It showed voltage at 13 volts, engine at 187 degrees and trans around 220. Cool, so I can relax, it’s just the analog gauges are hinky. Today checked breaker for instruments in elect. bay. Checked ground continuity from all gauges to the ground bar under the dash. RVDiagnostics guy guided me through measuring ohms from signal wire (each gauge) to ground. All checked out. Disconnected 3 big black bundle connectors in elect bay and reconnected, no change. Also found a large grey round connector under front left fender, opened and closed that, no change. Looked under bed to inspect any bundled connectors. Nothing but bundle of wires leading forward. Looked under engine on passenger side, saw no connectors from there. Sooooo…, anyone have any ideas of where/what to look for? Thanks in advance!
