Guest dirtyt Posted August 3, 2006 Share Posted August 3, 2006 According to my chiltons the small guage wire comming out of the plug on the top of the alt. goes to the body control modual then to a charge light. im having issues with charging and i blame this wire. i thought this to be a trigger wire for the internal regulator like a older gm alt. so i hooked it right to battery feed but it doesnt matter if its hooked up or not im still getting a low charge. my concern is that the bcm some how controls the internal regulator. What have some of you done in the past for your alt. circuit. Thanks Bryan Quote Link to comment Share on other sites More sharing options...
Bartman Posted August 3, 2006 Share Posted August 3, 2006 I have my small gauge wire connected to the ground side of a "charge" light with an ignition hot connected to the power side of the light. Not sure if wiring it this way would be any different than how you have it wired. I know that a while back my alternator went bad and stopped charging the system. When this happened the charge light always stayed on. I brought the alternator in to get it checked, and sure enough the alternator needed to be replaced.
