Hey guys. Had my 06 Tj sport 4.0, auto tranny, 86 k . No problems until this. No electrical upgrades unless you count removing the stock spare retainer. Before, it was just the battery, I'd jump it and it'd run fine. I could leave it for 20 or so and come back and it'd start, no problem. Longer than 40 mins and usually it needed the jump. Then, a recent development. In the morning, I can usually get the starter to click. In the afternoons, or after its been running for abit, the starter won't engage at all. Tried jumping it, still nothing. Also tried the solenoid trick on the starter, still nothing. Replaced my 40 amp fuse and that wasn't it. Can't tell if I need to replace the starter and battery, alternator, or maybe wiring. I've chased down most wires and the only damage I see is a little wear with wire exposed on a small black wire that clips into the starter. Wouldn't trouble ya'll with this but I'm on a pretty tight budget and wouldn't want to spend money on something that doesn't need replacing just yet. Also, auto electric isn't my strongest suit, so I apologize for any vagueness. Thanks for any good ideas or help.
