Electrical problem
1997 Mazda 323 4 cyl Manual

after alot of investigation found that the alternator is overcharging. when loaded with electrics the alternator starts squeeling and gets worse the longer you leave it. had the alternator checked and found to be not at fault. with the alternator squeeling in this way does eventually course the belt to break. did wonder if there were any other kind of regulation for the output of the alternator. am at the end of my tether with this problem, plz help if you can shed some light on this matter. thanks . steve
