I had lots of problems, they sent me 3 new ones, and then I found out that the problem was mine. Ran 2 No 6 cables from the battery in the trunk to the altinator. Pos and Neg hooked directly to battery and altinator. NO MORE Problems. Iceman

 

I have had one on my Belair for years great product. Not cheap import crap
