I had the rear connector cover panel from a 37" ViewSonic TV which happened to be about the same height, so I cut a piece from each end the width of the case and filed the edges to fit. Since it is a fairly soft ABS plastic, I was able to shape the rectangular holes with an exacto knife after drilling small holes around the outline. They are not yet glued in -- just held together by being pressed on with zip ties on the bus bars. I also shortened the case cover and the M- bus bar by an inch. Used an old table saw with a metal cutting disc in place of the blade -- works on plastic too! I had managed to get the current sensor closer to the circuit board by cutting the steel bar short so it would slide over the insulator board.

The smoke was probably not from the controller. I suspect a momentary short circuit across one of the 12 volt wires near the back of the controller, although I could not find any trace of a burnt wire anywhere -- probably vaporized.
