|3 Wires Fused to Converter NEG Lug|
I started by checking the fuses and noticed that 3 of them sparked while the rest did not. In addition, the 30 amp main fuses also sparked. I opened up the fuse block at the fuse block in the converter housing and found 3 wires with their insulation burned thru and fused to the Battery NEG lug. That certainly explains why the sparking and shorting. But then the question is: why is that lug and wire so hot that insulated wires melt and fuse to it?

In addition, there are lots of black wires that go back to the battery positive. I wrapped as many as I could figure out with red electrical tape so I can tell the positive wires from the negative. I found a short cable that went to a ground wire but unconnected on the other end. I don't know if something is missing a ground or if
it was sloppily left there when they replaced the converter and inverter.

I still haven't found where there is a positive wire going to ground to explain the hot wires but at least I can fix the obvious problems and go on from there. I now can follow more of the wiring in hopes that I can find it.
