• THE 32 AMP SYSTEM FEATURES A SERIES TYPE REGULATOR/RECTIFIER THAT UNLOADS THE STATOR WHEN THE BATTERY IS AT FULL CHARGE LETTING THE ENGINE SPIN EASIER THAN THE OEM SHUNT TYPE WHICH CREATES A CONSTANT DRAG. THIS NOT ONLY EXTENDS THE LIFE OF THE CHARGING SYSTEM , IT INCREASES FUEL MILEAGE AND FREES UP HORSEPOWER

• THE ROTOR HAS BEEN UPGRADED WITH AN IMPROVED METHOD OF GLUING THE MAGNETS TO PREVENT THEM FROM COMING OFF LIKE THE OEM ROTORS ARE KNOWN TO DO
• THE ROTOR CAN BE USED AS A REPLACEMENT ROTOR FOR THE OEM 22 AMP AND 32 AMP CHARGING SYSTEM , BUT ALSO WORKS IN CONJUNCTION WITH THE COMPU-FIRE 32 AMP AND 40 AMP CHARGING SYSTEMS
