Quoted from arzoo:Same with me, flasher use to work fine but then one day the pin would not boot with the flasher connected. Since then the original MPU board has been replaced. The PS board has been replaced. I've re-pinned every connector in the head. About to do a pf swap and replace the displays. But still no lick with the flasher, must be something bad (cap?) on the strobe board.
Caps and flash bulb are common, as are broken header pins on the aux board that drives the strobe activation.
