Alternator belt squeal
Guys my 89 vert has a squeal from the alternator at high RPMs. Had alternator tested, it痴 fine. Tried several types of belts . Cures it for a while, then comes back. I知 afraid I知 tightening the belt too much.
suggestions?

Check the belt tension/deflection per the FSM procedure, belts that are too tight or too loose will squeal.
Another point is if you removed your air pump, and are only running a single belt on the alternator/water pump, you really need to get a dual belt alternator pulley. With the air pump removed, there's not enough belt contact on the WP to give enough traction to reliably run both loads with the FSM specified belt tension.
