I wont list this as a solution, but it seems that working in the area of the alt may have moved around some wiring...the alt may be OK but perhaps an adjacent wire (maybe a ground) is not well connected. Also check crimped on wire loops on alt connectors..they like to corrode at the crimp where it crushes on the actual wire.

Here are a couple of ideas for you to try. First check in the power ditribution box under the hood, there is a fuse for the charging system, either use a circuit tester or just pull each fuse one at a time. Usually it is a 10 amp fuse as it is on my 94 cherekee. if you find any bad fuses replace them with same type and amperage. you should also check the fuse box on the right side of the dash, door has to be open for acess to the cover on the end of the dashboard, check all of those fuses also. If you live near an AUTOZONE auto parts store, take your jeep there and they can test your alternator on the vehicle , or you can remove it from vehicle and take it inside, they can bench test it. If you have a volt meter you can test it yourself, start vehicle, set meter to volts at least 20 or higher , place black probe on negative post on battery, red on positive, look at readout, a good alternator will put out 13.5 to14.0 volts, which is how much it takes to run vehicle and accesories and charge battery. If alternator doesn't put out 13.5 to 14.0 volts it is defective. I hope these ideas help.

Ive had this similar problem in the past with my 2000 Grand Jeep Cherokee. Ive found by putting the Jeep in neutral ...it started right away. Good luck

on the field wires ones a posative and one a negative and the single post gets connected to a wire that runs straight to the main fuse box in the engine compartment then is fused to another wire that goes to the battery have that fuse checked it could be your problem as far as the feild wires the positive side only works when you start the vehicle up to engage the field

It seems that your battery is not getting its charging amount from the rectifier which comes from the dynamo when the engine is in running condition. So just your rectifier and check the output of the dynamo to be sure thats OK............sodeep
