Hi guys.
I’ve trawled the internet for information on this. The wiring diagrams I’ve found are really poor.
My suspension compressor isn’t running. I’ve found that the suspension relay isn’t being switched.
The relay is good.
When the load side is shorted the compressor runs ok.
If I put a supply to the positive side of the relay switch+ the pump works ok.
So the conclusion is the relay isn’t receiving a trigger signal.
My problem is, where does this switch signal come from.
If anyone can give me a hint please.
