1992 Ford F150 6 cyl Four Wheel Drive Manual 150000 miles
I have a 92 f150 with alternator problems. I have installed 4 new ones and all but one of them would squeel at first start up after the installation. Ofcoarse the place I got the alternators from said my belt was slipping. Had it checked, belt was new, and it wasn't slipping. The one alternator that did't squeel lasted about 2 months before it went bad. Have installed 2 since, new, and both squeeled at start up. After they reach engine rpm and voltage gets up, they quit squeeling. I have taken the vehicle to a mechanic an had the charging system checked and it checked out ok. He used a self testing system machine which applied different types of loads to the charging system and was fine. So at this time I am stumpted. The last alternator I put on was bench tested to see if it was working properly before I put it on, and it tested ok. Any information would be helpful to me. Could I be getting bad alternaors?
have the same problem?
