Field PM magnet broke on a plasma flood gun during operation causing the controller to ramp the heater filament current to max (100A@5vdc) to strike a Xenon arc. The highest resistance point was one screw to the diode stack inside the unit.
Bad board on the left, similar board on the right. Completely melted the copper trace top and bottom.
Replaced both sides of the board connection with heavy terminal lugs, kapton tape and solid wiring to the traces. Back in business.
