Air Conditioner blowing fuses and it's HOT out!!!
Ok, I did a search and found this thread. But since it sort of died out, I will start a new one:
https://rennlist.com/forums/924-931-...s-blowing.html
So I was driving home today from tech session (it's a track car) and enjoying the cool air. Next thing I knew it was blowing warm and the light on the switch was off. I found that the fuse was blown. I tested the wire with the procedure outlined in the thread above. When the wire to the compressor clutch was tested (disconnected) I had good voltage and the fuse was fine. I checked the resistance and got 1.8 ohms...compared to the 3.6 Todd indicates in the thread. So I don't know if the coil is bad or the clutch or what.
Where do I test next?
Further.....if the clutch is bad, I need a new compressor, right? Is there is difference between the years or can I stick any year's compressor in there? I have a 1990 S2. If the coil is bad, can I swap it without releasing all the freon?
Thanks!!!

Yeah it seems that way. I ran it (at idle) with the clutch wire disconnected and I could feel the drag on the engine when I punched the button.
I tested the resistance again across the clutch (grounded to the body) and I got 1.8 ohms. Did the same test grounded to the compressor itself and got the same.

I got a new (old) compressor from someone and I was going to try and change coil. I took apart the old one on the bench, but I wanted to replace the part while in the car, so I didn't have to recharge the a/c. I can't recall since I haven't done this on a working system.... If I disconnect the mounting from the engine, can I drop the compressor enough with the lines attached?
I need to do this to get the gear puller on there. Right now there is no room to work with the radiator.
