amazinblazin10 Posted May 9, 2011 Report Share Posted May 9, 2011 I recently swapped out my stock alt for a DC power alt off of a 2001 blazer. My blazer is a 1996. The 2001 blazer had a 2-wire harness going to the alternator and it is by my understanding that if you disconnect this harness it will charge at 15 volts. My 96 only had a 1-wire harness going to the alternator and it is charging at 15 regardless of plugged up or disconnected. Is there that much of a difference in the alts or is there something I can do to make the battery light go off? 1997 Dodge Ram Van 2500 Big III addition with 1/0 awg wiring all throughout Lightning Audio Strike S4.1000.1D Jenson XA2250 2 - 12" Mtx Jackhammers JH55 3ft cubed box sealed under the rear bench seat Pioneer DEH-P6000UB head unit MB Quart FWA 160 components up front Link to comment Share on other sites More sharing options...
Guest DC Power Kyle Posted May 10, 2011 Report Share Posted May 10, 2011 Give us a call today. We simply just need to send you an adapter harness to get the charge light to go off because your factory plug is missing the sense wire so the alternator is going into failsafe protection mode which reads the voltage internally instead of remotely.
