When the inverter shut down, the independent SOC monitor was flashing "LOW" and its alarm was sounding. I was not in the coach when the system first went down. Soon after, I could smell what I describe as an electrical burn which is a familiar smell. My first response was to start the generator using the merge switch.
For some reason that I could not figure out at the time, both the house and chassis batteries were weak and would not start either the generator or the engine. As soon as I turned the inverter off, the generator started and a little while later the engine started. To my surprise, the dash merge switch is a three position switch which was in the bottom position and thus all batteries were merged. I need to mark this for the off position so it will not happen again. The merge switch still works even though it has been on for ever.
In the bay where the inverter is located, I previously installed a sliding drawer which houses a portable freezer. I hope on Tuesday that I can find someone to install the inverter for me. But if not and I have to do the work, I will plan a way to clamp the new inverter to the drawer when extended to the outside so that when it is rolled in, it should be simple matter of bolting the mounting flanges to the bulkhead with the Magnum already attached. I will have to figure out a way to safely remove the old inverter. Without the sliding drawer idea, I do not think I am strong enough to install it.
Yes, Magnum instructions makes make it clear that the cables are the last to be connected. I am now trying to figure out how to reconnect the AC cables from the old to the new.
Two days before, when I had two new tires installed and the inverter was on, the batteries were low after only two hours. I was puzzled at the time, but I think the inverter was the problem then as it is now. All 110, 240 and 12v systems work fine when on shore power or generator. Driving from Eugene to Modesto, the engine alternator charged the house and chassis batteries which leads me to conclude that the problem is with the inverter. The burn smell could only come from the inverter.
Please post or call me if anything else comes to mind - 303-547-5810, and thanks again.
