As Oil Eater suggested, check out that wire closely. Typically it runs through a very tight spot between the compressor and the compressor bracket. It may be possible that when he tightened the belt, it got rubbed raw around there somewhere.

But, (here comes the bad news) what commonly happens is that something goes wrong in the compressor clutch and it starts drawing too much current. If you are real resourceful and have the time to mess around with it, you could probably grab another clutch assembly at a wrecking yard and swap it. If your system doesn't leak freon and the compressor is still running fairly quiet, this may be a way to get another year or two out of it. You would have to compare the cost and hassle of going this route versus having a new compressor, dryer, and misc seals replaced and converted to R134. I would probably try the "resourceful" (cheap) fix one time.
