Hello all

Can anyone point me in the right direction for fault code E41, (Compressor feedback, low pressure side)
plenty pressure there but no power going to the LP switch

Could you apply the correct voltage to the LP switch to test the switch and controls work correctly?
Then trace back the wiring from the switch to find where your loosing voltage?

Yes thats a good start, I had 2 coaches this week with the same fault was kind of hoping someone could put there finger on the pulse with the issue as its very time consuming especially without the wiring diagrams
