Had gennie running while driving and left inverter on. 15 minutes later we smelled electrical burning smell. Stopped and inverter giving E5 OL error which I interpret to be overload due to short circuit. Checked inverter and see that negative DC cable from battery is melted.

Before I start tearing into this I thought I would ask for advice on steps to go through. Batteries are showing full charge. With inverter off and gennie running everything works. Same on shore power. On shore power inverter gives same error when turned on.

Thinking I will first repair DC cable to inverter and remove all power to inverter for awhile then restore and see if it’s ok.

Everything worked fine this morning on inverter alone. Can’t say I remember running gennie and inverter at the same time but it’s probable that I did since I like it to the switch over to the inverter when I turn off gennie. Seems like this should not have happened as inverter should have passed power through from generator without overloading DC cable. I have two 135 amp hour AGM batteries that still look fine.


Let me know if you need more info. This is a 2016 Windsport 34f.

Am traveling headed to Yellowstone KOA where I will start diagnostics and repair.
