[QUOTE="JKTim, post: 429812, member: 17668"] Charge up the battery and see if it starts on it’s own. Right now I would suspect a bad cell in the battery. If the battery checks out the next thing would be starter drawing too much current. Before buying a starter I would make sure the cables are not corroded. That should get you going in the right direction. If you can run it for 3 hours after jumping it I would suspect the charging system is ok. Easy test is volt meter at battery not running. Start it and voltage should be around 1 volt higher. [/QUOTE]
