Question about 1990 Pontiac Bonneville
I had an exact problem to yours...solution...First find out at what RPM your alternator is turning because most alternators need a minimum rpm to put out current...if your idle is too low, the alternator won't charge...you might have to re-adjust your TPS sensor to adjust your idle....if that's ok, then have your alternator checked for the amount of current it's putting out...mine was tested at 2000 rpm and was putting out -6 amps ( yes, that's right, I said...negative 6 AMPS)....it certainly won't charge anything like that....I ended up replacing my alternator to solve the problem...but before you do...you should have other tests done before spending money on an alternator....good luck.....silvio
