replaced neg battery cable and now no start
Hi all... yesterday i replaced my negative battery cable as it had been replaced at one point and was done very poorly, anyways it was causing issues to where i had to wiggle it to get my jeep to start. so i replaced the negative cable and everything was fine, i got the new cable on without any issues and the jeep started faster than i ever seen it, so i drove it and started it a few times and everything worked great, fast forward to today and now it won't start.. so i figured i must have accidentally left the key in acc so i tried jumping it but that did nothing everything was dead inside... any ideas on what could have happened?

Does the rest of the electrical work? ie. Headlights Horn ect? If everything is dead as you say, then go back to where you changed something. Start looking there. If the battery connections are good try dis-connecting a cable and touch a test light bewteen the cable and the battery post (Negative side). With the key off and out of the ignition, the test light should stay off. (If it comes on really really dim it could be radio clock or security drain thats okay) If it comes on bright there is something either shorted or turned on.

If you made your own, what gauge cable did you use and what terminal ends did you use. How did you crimp the terminal ends on? If you did your own, what battery connector did you use? You must of made the small cable that goes to the right fender as well?
You get the idea....tell us more about this replacement cable. Take a photo of the installation and post it here ifyou can.

Where did the replacement cable come from? OEM, junk yard, or made your own? If you made your own, what gauge cable did you use and what terminal ends did you use.

Good to hear you got it taken care of.
You have several grounding points that need to be maintained. The one you forgot to fix (battery to fender) also one at the oil dip stick, one at the rear of the head to the firewall two on the ignition coil and the mounting area between the starter and the engine block. Just one of those ground being bad or missing can cause a lot of electrical problem. You may as well and clean all of them while you are taking care of one.

That is the main battery to chassis ground, called G100. As you've found out, without it nothing happens.

It would be a good idea to disassemble the two attach points of the bonding strap and scrub the ring terminals free of corrosion using #2 Scotch-Brite pads, and sandpaper the firewall contact surface free of corrosion. Wire wheel the bolt free of corrosion or replace it with a new one (10-1.5 MM) and double nut the connection on bolt #14 (as shown in the linked pic) using 7/16-14 nuts.
