I replaced the control board due to flashing lights and checking continuity in as many of the switches as I could make sense of without a schematic. I am an avionics technician by trade. After replacing the control board, it seems to have worked for a couple of cycles then had a flashing light, I can't remember which one but never thought it had a pattern. Research online indicated there was a reset sequence after turning power on but not sure it worked. Now the Normal light flashes constantly without a pattern. Any help you can offer would be appreciated. I do not have the tech sheet.

Thanks, Phil
