I need to know if anyone has had a the same problem. A few weeks ago my BJ74 had sat for unstarted for a week and when my friend went to start it there was no power. He checked all the connections and found one that he thought was loose and was the problem. He tightened it and put on a charger just to make sure it would start. The 74 then started and ran for about thirty seconds and then died. He found that one of the new red top optima batteries was pooched and wouldn't allow any current to go through it at all. The battery was replaced and truck runs fine tonight from what he told me. Would any of you guys know if it was the battery ( which was 1 month old) that was the problem or the connection that may have caused the batteries failure or something else. It seems really strange that a new optima would crash like that completely enough that no current at all can pass through it. Everything points to the battery since none of the fuseable links were burnt. Any comments would be welcomed. Don't really want to put a bunch of $180 batteries in due to a different electrical problem.
