      Hey guys, im having an issue with a 30hxc series 4. My oil pressure transducer for circuit A1 is reading 0 no matter what, we have voltage readings at the board which match A2. Also the board still reads 0 with transducer plug unhooked also shorted. I replaced the SCB board figuring it wasn’t working correctly but now thinking its the main board or possibly communication issue? All lights blink in unison which tells me theyre all communicating… kinda lost at this point and hoping someone might be able to toss a few tips my way!

      • Is A1 compressor disabled? I have seen strange reading when a compressor is disabled. when you re enable the pressure will re appear. hopefully this will solve it.

        • I currently have to have it disabled to run it, but i did not take it out of disable mode when replacing the board. I will try it next time on site. Thanks dude!
