1987 HJ61 A/C is not working, and suspect a short circuit somewhere.
I recharged the refrigerant, A/C worked like a champ, so suspected low pressure switch was cutting off the compressor.
3 minutes later, A/C compressor kicked off again (fan still blowing) and I checked the fuse and it was blown. Replaced fuse, and it blew in 10 seconds.
For ~experimental purposes~ tossed in a higher fuse (15A) to see if it would run at all, and it blows immediately.
It seems there is a short circuit but I have no idea how to diagnose that beyond randomly poking things with a multimeter. Any advice is appreciated - my access to qualified mechanics where I live is very limited so stuck troubleshooting largely alone.
