I can't see enough detail in the videos to see your wiring or even the lights that are going out. [list][*]Are the solenoid status lights you referring to the ones on the PCB, or something on the solenoid itself? [*]Are these single solenoid valves (with a spring return) or doubles (which will only switch based on positive electrical signal)?[*]If they are singles, the most likely case is a loss of voltage causing a PCB brown out. This happens when your motor is running, so this makes sense. Have you been tracking the voltage? I see that in 12V mode, the PCB just passes battery voltage to the solenoids; in 24V it is regulated. I didn't find the brownout voltage for the PCB itself.[*]If it's not some sort of brownout, it may be a loose connection anywhere from the PDP to the solenoid actuator somewhere. It may also be a software issue, though this seems unlikely. If you can't find any electrical issue, I would suggest creating a smart dashboard widget to monitor the programmed state of each solenoid valve.
