87 Ram 50 4x4 "junkyard" rescue,

I honestly don't know... But I did finally get the original A/C wiring to function. I can press the switch on the dash and it sends voltage to the magnetic clutch, but every time I turned it on with the engine running it would pop the fuse. I even tried a 35 amp fuse, it worked for about 4 minutes until that fuse ended up blowing.

Right now I have it hooked up to the relay and switch for the off road lights, and it works just fine on that wiring... I'm going to add one more relay and use the original switch to trigger it, because for some reason the original wiring simply can't handle the load of the magnetic clutch anymore.

It does cool the air slightly, but not very well and I think recharging it will help a lot. But it works, so I'm happy.

if its blowing a 35 amp fuse its drawing way too much current! something is shorted to ground somewhere or the clutch coil has some shorted turns in it. i would ohm that out then ohm the wiring if the clutch coil tests within tolerances. you will want the factory ac circuit too work to keep the evaporator from icing over solid and the low pressure switch to protect the compressor from destroying itself.
