      I am working on a 806b, starts and runs fine, the display screen comes up, but I have no oil pressure reading, verified good oil pressure with a mechanical gauge. The sync board has a green light that indicates dc voltage is lit, the other boards are not lit. I verified 24vdc to the backplane board, I suspect the voltage regulator on the backplane has failed. is there a test point to check voltage on the individual modules, or does the backplane board need to be sent in for repair?
