Well my brother has a plymouth acclaim 2.2 and yesterday his car had no power my dad drove (an hour and a half) to his car and messed with the terminals a bit and it got started and ran fine. This morning it once again had no power so he played with the terminals a while and after about 10 miutes i decided to go out and give him a hand so i took out the specialty tool (channel locks) and messed with the terminal again and after a while i just turned the terminal to the left and it eventually stayed connected and he left. so whats the problem is it the terminals need to be cleaned does he need new terminals or what? Any suggestions on how to clean the terminals if that what needs to be done also appreciated. battery is fully charged. and also if the terminal does lose it's connection while he';s driving will it die or will it keep running fine until he shuts it off?
