It's so much more fun when there are all these trials and tribulations! You may be able to just cut the bad mosfet out of the circuit and go on like nothing happened. Once it's cut out, just check the resistance from M- bus bar (the one sticking out away from B+ and B-) to B-. HOPefully it will be a big resistance. If it is, then I say, full steam ahead!

I say just keep cutting the legs off the mosfets one at a time until you get large resistance from M- to B-. If you have to remove 5 of them, that still leaves 250amp at 125v of maximum power for a test. Just be careful with the DC throttle. If you cut out half of them, only push the DC throttle to no more than 50% of full throttle. full throttle will still try to command 500amp.
