Well I'm sure that some of you guys remember that I was having some electrical/computer related issues with my Dak, and after 3 visits and lots of arguing we finally figured it out. It turns out that the passanger side window regulator was shorting and sending the bad codes back to the computer which was storing the wrong codes and messing itself up. And they even had my truck ready a day early! Gotta love warranty!!

 

My 02 Ram's regulator in PCM is shorting out and not charging the alternator windings how did you/they find the short?

 

you have a different issue, probably related to the automatic shut down relay, does your tach work?

hopefully someone can move this to the correct section for you, do you have a 1500 or 2500? in 02 a 1500 is a 3rd gen, a 2500 is a second gen
