We’re using these brand solenoids from AutomationDirect with a PCM that has been sitting around a while. We switched the jumper on the PCM to 24v, but we only get 12v out of the solenoid outputs (measured with a multimeter). The LED on the currently-outputting PCM channel lights up when triggered via software and the LED on the solenoid lights up as well. All other functions (compressor and pressure switch) appear to work normally. All solenoids work via the manual valve (red indent).
Is there anything else to check? Should we cut our losses and just get a new PCM?
