That relay should be the auto shutdown relay it feeds power to quite a few things and I doubt the jeep would even start if it was bad...do you have 12v switched power at that wire? If so I would connect your RED wire there and then hook the original field control terminal back up and remove your new voltage regulator
it also looks like the GRN/OR wire splits and also runs to the ignition coil..is that right?? not sure if the "split" looks factory or not...and obviously someone has done some "work" around this area.
update: new ground wire installed, unfortunatly it didnt fix it. also i guess i bought the cheapest damn test light and it blinked once when i tested a connection now it wont work at all. so im not sure if the wire from the fuse box has 12v or not.... now what? the jeep runs smooth showing about 10v, however when i put on the lights and especially the A/C it starts to drag...making me think its running straight off the fresh battery. im starting to get frustrated now, but i feel like im so close!
just made a make shift test light, and not getting any power to the GR/OR wire in the fuse box however i am getting power from another wire in the same relay so the relay cant be bad right? where do i go from here
still not fixed, unfortunately been driving my mom's car... tested and its not getting fire. i got a new ignition coil and that wasnt it. i was talking to a few people and the said something about maybe messing with those wires could have fried the computer if i didnt have them in the correct spot so i went ahead and removed the pcm and noticed its a REMAN so someone else has obviously had a problem with it in the past. a new (reman) pcm is 250 from jeep and then another 110 to program to my jeep. i really dont have the money for it especially since im not 100% thats the problem. any other ideas? before i do the unthinkable and just sell it as is.
