b-dubs89 Posted June 6, 2012 Report Share Posted June 6, 2012 if you got an accurate reading of 8 volts from your battery that is probably not enough for the computer to operate or any other systems .one way i test an alternator as far as working or not is get it running and carefully disconnect the battery if the engine dies after you disconnect the battery the alt is not charging and the engine and everything was running off the batt Quote Link to comment Share on other sites More sharing options...

Kyblack76 Posted June 6, 2012 Report Share Posted June 6, 2012 Lets sniff around... at OP...Why did you put a new battery in? cuz it went dead ? with that, When you intalled the new battery you just picked up, was there some bubbling, foaming, or a shit ton of corosion on the old battey posts and such??
