Had to replace a terminal board that got all burnt up.

While im in here, adding a bunch of ferrite beads anywhere they fit (this bitch is noisy and the beads will help a little bit, but not THAT much) and I noticed the lack of effective EMI suppression at the drains of the mosfets! I mean, there's a LITTLE bit but I wouldn't exactly call the chassis drain points "bonded" - some of these are on the order of 200 miliohms when it should be a dead short to the chassis!

This is because the inside of the mounting screw studs are painted ffs.
