**** #%&*@+ PS A/C belt keeps slipping off or breaking!! HELP!

I just purchased my '91 Spider about 2 weeks ago. It came with no PS A/C belt and some lame reason (I fell for) by the PO why it was off.
Anyway, since then I have replaced 4 belts (and a broken A/C compressor & tension pulley) that have either slipped off or got chewed-up, knotted and broken!
The pulleys seem fine and in-line, what could be causing this? Any others with this problem?

HELP, desperate and frustrated!

Frozen compressor?

Nope, new compressor, and happened when we only used the top and bottom pulleys!

Does it run at all before popping off?

The question is, how to figure out what is happening. So if it runs and the belt stays on at idle and then when you rev it, it pops off.. If you start it with it on, and idle it, and then turn it off and check the tention making sure that it is tight. Then start it again and watch and see where it is coming off.
At the pwr steering pump, at the idle pulley, etc. Good way to get slapped. I have put one on and been a groove off. Does the whole thing work towards the front, or the back when working it's way off? HOW RUSTY are your pulleys. Rust will cut through a belt quickly.

It works its way off backwards, towards the engine.
We think now the pulleys may be misalighned, possibly the lower one.

Are all the PS and AC brackets tight with no movement (wobbly?)

Also is there any dents on any of the pulleys?

Seems to be tight

"Also is there any dents on any of the pulleys?"

Can't say, but possibly not.

Something is misaligned between ribbed pulleys of power steering pump, a/c compressor, crank pulley and serpentine belt a/c idler pulley. Check compressor or power steering units for evidence of recent replacement, mounted wrong or crank pulley not installed correctly.
