Alright Ive narrowed the problem down.... I check all of my wiring and everything is securly tightened to the fullest. Problem is the amp keeps saying current when it cuts off. That leaves me with too problem either I need a better battery or a better alternator. So 2morrow Im going to go up 2 autozone and run a test on both of them. The actual question that I have is whats the best battery that I could get for my 03 cavy, and whats the best alternator that I can get. This way I will at least no what to buy depending on what the problem turns out to be 2morrow.

alot of ppl run group 34 optima yellow tops....169.99 at autozone i think

try pepboys, Most are selling yellow tops for $120.
