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!
