Why is your 2007 grand prix overcharging your battery?
Voltage regulator is more than likely defective. The Regulator is built into the alternator so you will have to replace the entire alternator. Just make sure it is really overcharging. You should read from 13.5 to around 15.5 volts with a digital DC voltmeter if the alternator is performing as it should. Must more than 15.5 volts and it is overcharging.
How do you know if the alternator is not charging?
Check the voltage at the battery with the engine running. It should read from 13.5 volts to 16 volts. If it reads lower than 13.5 volts the alternator is defective.

Defective voltage regulator. Check the voltage at the battery with the engine running with a digital volt meter. You should get 13.5 to 15.5 volts. Any more and the alternator is overcharging and needs replacing because in almost all cases the regulator is built into the alternator.

Replace the alternator. It sounds like a defective regulator, and it is located inside of the alternator. The volts should never go any higher than 16.

I have the exact same pproblem with a 1988 tempo, replaced the alternator and battery, still the alternator only reads 5 volts when running. Can't figure it out, do you know of any websites that would have a diagram of the alternator for a tempo?
