Welcome to Jeepforum! You did the right thing by having the alternator tested. That rules out one potential problem.

Here is a basic diagram that shows how the alternator should be wired:



Note that your Jeep may have a different type of alternator, so we should confirm that first.

I have to ask...how do you know the alternator is not charging? What method of troubleshooting did you use to determine the problem.

Here is a quick and dirty method to determine whether alternator is working.

Start the engine and remove the negative battery terminal. If the engine continues to run the alternator is fine, if the engine dies, the alternator or wiring is bad.

Additional information would be helpful to determine what you have going on. Details of the symptoms you are experiencing are needed.

Good Luck and welcome to the Jeep Forum.......

i have tried that method also, have started the jeep and removed the battery cable, she just died. so i have come to the conclusion that it had to be wiring since i had the alternator tested. i will tell you what kind of alternator it is in the morning and maybe that will help out a lil bit. thanks for all ur help so far

Start checking the terminal ends on your cables. Many times they look good but have corrosion or are only hanging on by a few strands. I have been fooled more than once by a bad cable.

Posting some pictures would also be helpfully.

I have a cs 144 GM alternator on my 4.2. it is a pretty easy swap can be found on lots of Cadillacs and is 140 amp +-
Mine was built by Rush power systems and has a remote voltage regulator, non avalanche diode pack and a life time warranty.
I have been told that one wire alternators are not the best way to go, especially if you pull amps from a winch, lights, air compressor Etc.
If you go with a larger alternator be sure to use a larger cable between it and the solenoid.
