This new charging system features an advanced proprietary stator winding of a new design that maximizes efficiency with near 80 percent sectional density of the winding coupled with very low coil resistance. This gives the alternator maximum low speed output, as well as a 90% reduction of magnetic pulsation with the stator windings built in cancel circuit to minimize electrical noise. The internal regulator is a proprietary design advanced multifunction digital regulator that completely integrates into the Dodge Ramís PCM through the OEM wiring harness to retain all the Dodge Ramís specific functions such as internal temperature compensation, lamp terminal monitoring, load response control, and alternator load factor.


The Denso Hairpin 180 Amp HP series alternator is specially designed to mount directly in the OEM mounting location of the Dodge Ram with no modification needed. All electrical connections shall be in the original locations. The alternator features a custom machined drive pulley for increased output at idle speeds and retains OEM belt length. The pulley is 7 Groove Hard Anodized 6061 Billet Aluminum and hard anodized coating for wear resistance and durability.


The 2000 Dodge Ramís OEM alternator is rated approximately at 100 amps with 65 amps at idle.
