I have a Multiplus Compact 12/2000/80-50. It gave up the magic smoke. I've run it flawlessly for 18 months in my RV, including a 2 week trip we just completed. On our last night of the trip, we stopped at a rest area and I started my Honda EU2000 genny and plugged in so I could run my Air Conditioning for a bit. I've done this many times. The AC didn't respond and I heard a buzzing from the Multi, smelled the electrical ghost, and the Multiplus showed an overload condition. I switched it off. I wasn't prepared to dig into things 800 miles from home on our final night of the trip.
Now that I am home. I confirmed the Multiplus is burnt up. I confirmed the generator output is at 126 volts with no load (is that too high?). I intend to remove the Multiplus and reconnect AC power to try and troubleshoot if there is a short somewhere. I have suspicions my Air Conditioner may have something to do with it, it was acting up a bit the last time I used it, but I was thinking the thermostat was going out, but it worked. Maybe there was more to it...
Is there anything I should do before I completely disconnect the Multiplus? Any thoughts on where to look for a cause? I fear installing a new Multiplus only to burn it up again.
