Caravan (or any) A/C clutch diagnostics

So just 12V+ to green and ground to black inside connector? Can do, I'll have to release the clip of the plug to see in there. I should have continuity though, right? A coil is just that, an open loop.
As I said, be careful of the spike diode. Use a meter to try and determine, or consult diagram. green vs black, don't assume one is ground

Also have you tried bypassing the low pressure switch? It COULD be bad, regardless of low side pressure
