Hello dear engine friends, I have a problem whereby I would be very happy about help. I bought and restored a compressor (alup , 3 cylinders , 500 liters , 940 liters suction power ) without electronics. Now I bought everything new to electrics (used ), only the solenoid valve and the pressure switch were still there. I have now wired everything as I think , only I have no idea how to clamp the pressure switch and the solenoid valve . In the appendix have I have numbered a plan as I have wired it so far( Grounding on the drawing omitted due to better overview ) Pressure switch and solenoid valve. I would be very grateful about any help. Add pictures from the original state to the ( almost ) finished compressor.
