Voltage regulators maintain a constant range of alternator voltage output and convert the alternate current (AC) produced by the alternator into the direct current (DC) the vehicle operates on. As the alternator turns, it uses coil windings and magnets to create the alternate current. The faster the alternator turns, the more current and voltage is produced. The voltage regulator uses diodes to convert the AC to DC, limiting the alternator's voltage output to 12-14 volts.

Voltage regulators fail when they can no longer convert alternate current to direct current or when they can no longer maintain a consistent voltage that the Porsche requires to operate.

Signs of a faulty voltage regulator include:
  • Surging lights
  • Flickering interior lights
  • Instrument cluster or panel malfunctioning
  • Battery light or check engine light illuminated
  • A battery not being charged

Checking battery voltage or alternator output are simple ways to test a voltage regulator. Fluctuating battery voltage or drops in alternator output when the engine is at idle indicates the voltage regulator has failed and is not regulating voltage or not converting alternate current to direct current.

Replacing Your Porsche Voltage Regulator

Some voltage regulators are external to the alternator and can be removed and replaced in series with the alternator output circuit. Other voltage regulators are mounted inside of the alternator and may be removable and replaceable, but some will require the replacement of the alternator to replace the voltage regulator.

Original Equipment Manufacturer is the company that made the part(s) that were installed by the car maker at the factory. Due to federal and international guidelines for good business practices, there are normally two or more OEM brands for nearly every maintenance part on a vehicle. The use of an OEM part will ensure that you have a part made specifically to fit your vehicle.
Left = Driver side and Right = Passenger side.
All parts are priced individually unless identified as a set or kit. "Per car" notes identify how many of a given part your car has and "Left/Right or Front/Rear" notes means the part fits the left or right side of the car. These parts are still sold individually and you'll need to select the appropriate quantity if you plan to replace more than one of this item.
