SR3RS Compressor fault
Discussion
All.
Had my side pod off to repair and drain compressor tank of water (normal service). Discovered once pod back on compressor not operational.
Trouble shooting reveals the following. We have 12v both on power side and control side of the relay. Relay tests OK off the car. On the expected negative terminal on relay the wire is orange not black. There is no continuity between this wire and ground. Running a separate ground wire to the orange wire terminal get the compressor running (only tried for say 30 secs). I am concerned that this orange wire is not a straightforward ground wire, is it switch via ECU or pressure switch on compressor tank. I know its not too common to switch the negative but I have seen it before. Anybody with experience with this that could help me.
Thanks in advance
