all i know is if you dont get a new alt or a cap you will fry your alt i have already been threw two alts and it would have been cheeper to get a cap I never liked the bat in the trunk takes up more room and dose not look as good. also a red top bat might help but they are alot of $$$. I would go with a cap maby a cheep on untel you get some mony than sell it on ebay or just have two in the trunk.
