Blower overwork

[JHZR2]

Im very familiar with the blower pulling too much current in w123s and causing a fuse to pop (or replacement with the strip fuse in the MB mod kit). Burned out a fusebox once...

This is different... was over 100 last saturday. Seems my 82's R12 charge is a little low (some bubbles in the sightglass). It was HOT. Had my AC set on auto for fan speed, and after being on a bit, I smelled what seemed to me to be burning electronics. Turned off or to low, no issue. Did this a few times and noticed it repeatedly.

Fast forward to Sunday, still hot, still lots of AC, just not AS hot. Run the fan on auto, its spinning fast, no smells. No nothing.

Any thoughts? I sure dont want an electrical fire. I got a fuse that Ill put inline at some point, but that can only do so much in one place...

Hopefully I dont have any issues. My car is running and looking so great right now, and will be even better when I get my chrome 15" bundts!

Thanks!
