AC clutch doesn't engage.

Okay guys I'm thoroughly confused. There is freon. The low pressure and high pressure switch appear to be functioning properly. (Also have bypassed) 12v makes it all the way down both wires to the electromagnet. Magnet is grounded. It still doesn't suck the clutch in to engage the condenser. I have tried two different clutches and magnets...doesn't seem to make any difference. What the hell am I missing here? As soon as both wires have 12v it should engage the clutch to my understanding? But it doesn't. I also don't think it is the clutches air gap because the magnets are not magnetizing at all. Other things would stick to them I would imagine.

 

Yes so there is two wires that go to the clutch. When I unplug the low pressure switch or turn the AC off on the dash it only has power on one line. When I plug everything in and turn it on on the dash both wires have 12v power. I will run a direct 12v from the battery and see if I can get it to engage.

 

When everything is how it is supposed to be for it to run both turn hot on this truck. So I must have a wiring issue?

 

Okay when I pull the green wire directly off the compressor and ground it the clutch engages. Both those wires come from the low pressure switch on my truck? And both have power when AC is engaged? One has no power when AC is not turned on. I gotta do some more trouble shooting here.

 

Is the low pressure switch supposed to be grounding the system or supplying power? I guess I thought it was supposed to supply power? That seems to be wrong? I confused as to how this is a new issue. I will check the grounding studs in the fuse box as well.
