Big 3 and at least a 135+ ah battery. Look around in the classifieds for batteries.

First do the big3 and get your regular battery and alt checked to see what they are and their condition.

If you have a 110 amp alt or larger kinetik hc1800 or 2000 if it is smaller than 110 amp I would lean towards an hc2400.
