poorfish88 Posted October 26, 2011 Report Share Posted October 26, 2011 Is it one of those Walmart Maxi fuses? If so those suck and I've seen them cause all kinds of trouble. Quote Link to comment Share on other sites More sharing options...
adreano17 Posted October 27, 2011 Report Share Posted October 27, 2011 1. Your alternator is weak, its time for an upgrade 2. if you are running a small gauge wire, then it may not be getting the sufficient amount of current.

Kyblack76 Posted October 27, 2011 Report Share Posted October 27, 2011 Would a bad alternator cause it to play fine when it's OFF and cut out when it's RUNNING???.. Isn't that his issue???
