If the check engine light is or has illuminated, check for codes.
Check the voltage regulator mounted to the fender
The regulator for the 1997 Ford Thunderbird is bolted on the back of the alternator. While the regulator can be changed separately it is more commonly changed along with the alternator.
i had smilar issue with my 99 mitsu mirage, changed alt, and battery, and still had problems, turned out to be the voltage regulator. To test use a voltmeter and if the reading is below 13 on a new battery and is fluctuating then it should be the volatge regulator Try changing the belt i just had the same thing happen to my 03 rs i change both belts and then everything turned out fine after that
Did you check the voltage regulator? As the apperance my change from Model to Model, the voltage regulator connects to your aletrnator directly. I believe the regulator tells the alternato exactly how much power is needed to safely operate the vehicle. I had same prob with my 77 mustang II. Swollen battery, rotten eggs, and too much power.. Replaced the battery and voltage regulator and my problems were gone. Hope this helps.
The 2001 Cavalier has the regulator built into the alternator. As this is an integrated component the alternator and regulator are changed as a single unit.
voltage regulator, sometimes its in the alternators, advance auto parts doesn't replace them in remanufactored ones.
Yes
looks.
have you changed the battery

AnswerA loose cable, the voltage regulator or altenator! If it is the voltage regulator or alternator in most cases they are housed together, so it you change one, you have to change both! Just about any of the chain auto parts store will test it for you at no charge or the car is broken
changed battery in 2000 chrystler sebring and now will not idle
