Quoted from fxvielander:Great thank you and much appreciated. The caps don’t look great on the solenoid board, I’m going to go ahead and just replace the board. Any way to get a sense that it’s probably a solenoid board problem vs a MPU board problem?
This sort of problem is usually due to the 5v & 12v supply to the MPU being crappy. As you've already replaced the rectifier board, the next step is the part of the power-supply located on the SDB. It is almost always the large electrolytic capacitor, but sometimes can be the voltage regulator (transistor). It can also be the connectors, the power-on reset circuit on the MPU, or even the sockets for RAM/ROM on the MPU.
