newls1 Posted May 26, 2010 Report Posted May 26, 2010 alt is fucked, send it in, or perhaps give DC Power a ring I love my staffie So anti FACEBOOK it isn't even funny
F540HD Posted May 26, 2010 Report Posted May 26, 2010 alt is fucked, send it in, or perhaps give DC Power a ring Most common causes are bad regulator or failing diode. Of course it can be many things. I agree with sending in the alternator. The downtime is a major reason why I recommend shopping local.
