Have tested an 12v direct supply to the compressor feed wire. The clutch pulls in and closes the gap. Which for info is just a tad wider than a credit card.
So I'd presume the coil is OK and the compressor may well be in good shape should a signal be getting to it to engage.
When I test the feed wire from the car to the small plastic push connector it gives about 13volts or so every 10 seconds. I have no idea if that is correct or not? I would assume that it should have a fairly constant live feed when running?
Oddly when the push fit connector which near the compressor, about a 6" tail leading wire, the clutch never flickers or engages. The connection seems pretty firm and I've even put a jump wire between the two ends of the connector.
Alas still no clutch engaging. Perhaps the very short pluse of the 13volts is not long enough to create a magnetic field to allow the clutch to be drawn in with?
Anyway .... the investigation continues... but at least some progress...
