Powermaster race alternators supply horsepower for your ride by ensuring the electrical and ignition systems have enough voltage to operate properly. This means your battery stays fully charged and predictable—you don't have to worry about your car not starting at race time. They feature a variety of high-amperage ratings, one-wire hookup, a gold battery post, and a heat-dispersant coating. Some models also include a pulley. Order the alternator designed for your vehicle application.
The XS VOLT alternator still operates as a one-wire, meaning that the only connection necessary is the charge wire (or battery output). The voltage adjustment allows the racer to change the set point of the voltage system while the unit is running. The set point is the level that the unit sees as the goal, the perfect level of the electrical system. On the XS VOLT, turning a small potentiometer on the back of the alternator can move this set point. The range is 13.5V - 18.5V, allowing one alternator to be used with 12V and 16V batteries -and anything in between. Charging sensitive gel batteries at low voltages or using the hybrid 14V batteries are not a problem for the XS VOLT. This means that one XS VOLT alternator will work with your car no matter what battery you choose.
