No Power. Battery,Altenator, and starter all good.

Desperate help for any trouble shooting tips. 2006 TJ (SE) wont crank. Put the key in ignition...nothing. Might beep for a second. I had the battery tested (purchased in August), the alternator, and the starter. They are all testing fine at Adv Auto Parts. I checked all the fuses. Could it be the ecm? 97k miles

Are your terminals clean? Did you check the grounds?

Do your headlights turn on? Are they at full brightness? If they are on at full brightness, what do they do when the key is turned to the Start position? Do they dim/go out or do they stay on at full brightness?

Mine was doing the exact same thing. I changed relays checked battery starter all cables. The weird thing was the rear window defogger witch would be the only thing to stay on. Ended up being the ignition fuse loose in its socket in the fuse box under the hood. Took about five days of after work trouble shooting to figure it out.

Grounds and cables would be my first move, then starter circuit, i.e starter relay and ignition switch. Really need to know if voltage is dropping or nothing changes. Do the above checks with the headlights. If you can, hook the meter leads to the starter and read the voltage during start. Do the same thing at the battery. Run one side of a jumper cable between the ground post of the battery and the engine.

Thanks! Ground appear fine. I am off to get a ohm reader an d test the ground. I cleaned the terminals really well. WHen i put the key in the ignition nothing happens. Headlights dont come on. If i turn the key a few times, the speedometer and the rpm needles will bounce once.

If you are 100% sure the Battery is good you must have some kind of connection issue start by inspecting every battery cable connection at battery-Junction block & engine.

Disconnect your terminals and take a wire brush to each terminal. My TJ would randomly not want to start somedays. quick disconnect for a few minutes with a wire brush to clean the terminals and mine would fire right up!

Clean them both, should be metal on metal. Use a wire brush to clean the connectors down to bare metal. Make sure the terminals on the battery have no corrosion on them.

So I just took a trip to the OBX last week and drove on the beach a bit. Had the hot tranny oil light cone on so I would pull over and let it cool down and it would be fine.

Now that I'm home I hear some noises. Tranny seems fine while driving but shifting from park to any position makes an almost crunching sound and I hear a sort of wobble coming from under the rear. Possibly the rear diff or axle? Not tire related as far as I can tell. Air pressure and all are fine. And the wobble noise comes even if I am just rolling out of my parking space at work.

Possible sand causing the crunching sound? But no idea about the wobble noise. Again a noise not an actual wobble.

Any help would be great before I need to bring it in.
