Same thing happened to me yesterday....Didnt have a real charger, only a trickle charger. Had the pigtails connected to the terminals before, but took em off because batt. wasnt charging (later found out the fuse was blown on the pigtails). So.....20 min of screwing around getting to the batt. and another 3 hrs on the trickle charger....the bitch finally started. Worst location for a batt. EVER!!! . Needless to say, the pigtails are going back on.
