well 3 days at 10 amps the motor still wont turn fast enough to start so i think the 31s r shot. ya i know first i killed group 31s thread. so where you guys recomend getting them? and locally new i found them for 1200cca for $140 and 950cca for $105. is that a decent price? anyone have used the interstate rehab batteries? also can someone link me the 3g alt mod i think this is needed now with all the electronics thanks.
