I've always wanted to try one of the JC Whitney kits that ups the amps on your old alt


I bought one of those kits. Had a local alt. rebuilder install it for me. He told me what would happen, and he was right. He hooked it up to his machine. It DID put out the amps. Only at 4000 rpm or more. They don't do squat at idle. Save your money and buy a Powermaster!
