After nearly a month my local Chevy dealer has come to the conclusion that my truck is not charging due to my ecm. Apparently they are getting a varying to no charge signal. They quoted me $2000 to have a new one installed. I don't have that kind of change just laying around at the moment. Is there any way that I can bypass the ecm and set up an external regulator so that my truck will charge until I get the ecm replaced? Any tips/info is greatly appreciated.
