Any ideas ???

I bought it..... :)

Man, I'd have no problem helping ya get that beast a rock'n. 2 bad it's 5 hrs on the road round trip
.
I went back and looked and it said out of stock. And I thought oh crap that figures.
Hopefully this fixes the problem.
My thinking is there might have been a wire get hot because of a connection at the bulkhead or at the switch and It caused the whole mess.
And the previous owner didn't look far enough to find the problem. And so just started chopping things to pieces and patching things trying to get it to go.
