Found the problems with the connections mentioned above, 1 bad termination and the wrong washer on a another, must have grabbed the wrong one when assembling it the other day.

I think I fixed the big Fuse holder, which BTW is not there to protect the Inverter board or FETS, the Caps themselves will make sure there is nothing left to protect, it's only to stop the heavy DC cables from causing havoc if they somehow shorted, the fuse works, I tested it, well, I spot welded a steel bar across two terminals when I tried to test it, it blew, so I guess it's tested

I'll repeat high load testing tomorrow and recheck all the connections once more.  

A poor pix of the new Chokes installed, 4 turns on each, they are on standoffs, so they look a bit taller then they really are. A blue toriod ring on each end of 4 black toriods rings. As mentioned before I used what I had.
