Where is the voltage regulator located at - 1997 Pontiac Grand Am

If I'm not mistaken, GM has had the voltage regulator internal to the alternator for years before '93.
The alternator has to be disassembled to repair the voltage regulator. Most do-it-yourselfers just replace the alternator.
Here's a picture that shows the regulator at RockAuto -

Jorge, You probably have an alternator on that truck,which means the regulator is built into it. Check the attached links,instruction and guides, Good luck

where is the voltage regulator located

voltage regulator is located internally inside an alternator and is usually not a serviceable part. you would either need to replace entire alternator or take it to a alternator shop to have them replace the voltage regulator

first check for voltage with the car running..anything over 16 volts is too high..most run at 14.5 to 15..the regulator (if not in the alternator already ) is a small block usually on the firewall .. to find locate the wires on the back of the alternator.. if they go to a box on the firewall thats the regulator..if they go straight to the battery positive, then its a built in regulator,,auto parts will check for free..

mostly the voltage regulator is in the unit that holds the brushes in the back of the alternator . Sometimes depending on the make the regulator can be found in the engine compartment. Best to contact an auto electrician to get the right regulator. and where it is located

You have a short or a bad voltage regulator. Check your battery connections. Not just on the battery, check the wires all the way to the connection points to ensure there are no worn insulation where the positive wires could possibly be grounding out. Get the Haynes Repair manual on your vehicle so you can locate the voltage regulator. Typically this is part of the alternator but in several VW vehicles I have had and worked on the voltage regulator is in a separate location. Test the voltage regulator according to the manual.

The voltage regulator is inside of the alternator, it is an integral voltage regulator, so if the voltage regulator is faulty, the whole alternator needs to be replaced.

The Electronic Voltage Regulator (EVR) is not a separate component. It is actually a voltage regulating circuit located within the Power train Control Module (PCM). The EVR is not serviced separately. If replacement is necessary, the PCM must be replaced. Hope this helped and best wishes.

The voltage regulator is probably in the alternator. I don't think nowdays you can buy voltage regulator separate. If the voltage regulator is bad, you'll need to buy an alternator.

The Voltage regulator is in the PCM.
