    Can someone confirm that there should be +50V Flyback suppression Voltage connected to J2-10 on this board?

    Exactly, except with a 50V Coil Drive, this flyback voltage will easilly be several hundred volts and more than high enough to instantly destroy these transistors and MOSFETs.

    I don't know where that Red/Orange Wire on the board side of the Z Connector is running off to, but I'm guessing it should have been punched into the J2 at position 10. Have Stern send you a new harness and board. Its likely your two failed boards are easily repairable, I wouldn't toss them.

    Curios, What was this new wire harness supposed to do for you?
