We build an internally regulated (self exciting) alternator for your 5.9 Cummins diesel to eliminate the PCM controller. In some cases the PCM fails which causes erratic, under and over charging, in other cases these motors are transplanted into another vehicle and you don't have the PCM. This alternator will solve that! One of our customers supplied this video, thanks for that.
