Voltage Regulator
for your 1991 Volkswagen Jetta
No matter what you're driving or where you're headed, your Volkswagen Jetta needs a proper voltage regulator to keep running smoothly. A highly critical component of your engine and computer system, the voltage regulator allows the alternator to charge the vehicle's electrical devices without damaging them. When it's time for an upgrade, look no further than StockWiseAuto.com for the ideal replacement part.
The voltage regulator maintains the voltage your alternator produces, regulating it between 13.5 and 14.5 volts. This allows the alternator to charge the battery but prevents it from overloading the sensitive electronic components of your Volkswagen Jetta with too much power. While your car's voltage regulator has a fairly long life, it may need to be replaced at some point. When it does, visit StockWiseAuto.com—with a wide variety of parts and accessories for nearly any vehicle, you're sure to find exactly what you need for the miles ahead.
