Help! This is driving me crazy. I rebuilt a -54 rectifier board (I have rebuilt several others with no issues) from a Xenon and TP3 is reading over 30 vdc. The board had some prior work and still had the original 3 amp diodes for the 12 volt rectification. I tested it before I started and it read about 15 volts at TP3. I replaced the original diodes with 3 amp 1N5404 diodes.
I have done the following:
* I reflowed all of the connector pin solder. There are no shorts in any connectors (tested with DMM).
* All of the 5404s pass the diode test (they are all new).
* I can detect no shorted traces anywhere on the board (tested with DMM).
* Confirmed about 15 vac at the unbanded ends of CR6 and CR7.
* Got over 30 vdc at the banded ends of CR6 and CR7. Cut the trace to TP3 and still got over 30 vdc.
Help!
