now got an 04 grand prix
what you guys think should i go ahead and get an isolator? i do not want the red top to die on my as its 2 months old. i mean for 50 bucks for an isolator, id be willing to pay that if i can save my batteries/make them last longer. so would it hurt in anyway? the back battery will still get charged, but not take away from the red top up front right?and if i do would a 200 amp one be good? i see either 80 or 200 mostly on ebay.
