No Start No Crank

2009/10 JK, any advice on how to, or not to fix this. I found the YouTube videos very helpful, especially the practical approach to tracing faults, but nothing prepared me for this. Thanx for a great site and excellent videos

For our reference, where on the vehicle was that picture taken? How easy is it to access and manipulate that harness?

Everyone will repair those wires differently, so you'll get varying answers. In your case, I'd be inclined to use bare butt connectors, quality shrink tubing and some 18ga wire (guessing from your pictures). You'll get strong connections and great weather resistance. Dead simple to install. Available for cheap on Amazon.

Pick one damaged wire and cut out as much damage as needed to get down to clean copper. Guestimate how much length of wire you'll need to join the two ends, leaving a bit extra because mistakes happen. :silly: Strip the wire ends, slide some tubing over, install the butt connectors and shrink the tubing up.

Then, wrap it all up in tape/fabric/conduit and zip tie as needed to make sure it won't rub on anything. But before that, crank the engine to make sure you fixed it. :lol:

For different colours of suitable wire you could buy a short length of trailer and strip. If you use crimp connectors buy/borrow a proper set of crimping pliers.

Agreed on the pliers. I've been using the Snap-On equivalent of these for years, love 'em.

Well, at least it's not under the car? :silly: Were these rubbed through, or do you suspect a rodent problem?

Far right in the engine bay (facing the Jeep) on a right-hand drive underneath the TIPM (i.o.w., between the battery and the computer.) I've taken out the TIPM to get to it. I since removed the battery as well and loosened that whole '(battery, TIPM) tray' to move it a bit out of the way in order to have better access. Thanks for your advice.

No rodents, that is purely as a result of chafing/rubbing againdt the body.
