It wasn't sparking too bad so I went ahead and hooked it up. It didn't blow up.
Using my light pen tester thing I went around trying to test for hot wires around the trailer. Nothing.
Pen light to positive battery cable and ground to shell.. nothing.
Pen light to positive battery cable and ground to Neg cable.. light!
Looked again at the diagram that came with the converter.
I hadn't hooked up a ground from the Neg battery cable line to the shell.
Put a wire in there and then I started getting light in the tester when grounding to the shell. Apparently the shell wasn't grounded or something?
Think it may be ok now.
-Grounds
-- white wire from side of converter to shell
-- white wire from top breaker (neg) to shell
-- white wire from
12v panel to shell
I appreciate all of the help TG and Splitrock.
I will now post this information on my restore thread and take full credit.
Off to work on windows..
