Voltage Regulator? Sign In

2001 Pontiac Grand Prix 3.1
The dashboard lights get brighter, the heater blows harder with acceleration. Service Engine Soon Light is on. Alternator Checks Good, Battery tests "weak". Does this sound like a bad voltage regulator?

You need to get a voltage reading at the time the light is on. It may be overcharging.

Between 13.5 and 14.8 volts.
