XS Volt 100mm Denso for 12/14/16 Volt Systems

For racers running 16-volt batteries, Powermaster also offers an XS Volt version of the new 100mm Alternator. The XS Volt 100mm model features a unique Voltage Control System that allows the voltage output to be adjusted from 13.5-18.5. This feature will help racers keep their electronics at full operating voltage which is especially important for the ignition and fuel pump. Adjustments are made through an easily accessible potentiometer and this new unit is a bolt-in upgrade for the proven 93mm XS Volt Powermaster!
