I recently replaced the battery and battery terminal ends on my 1996 Bronco XLT 5.0L. I did not have a wiring diagram on me, so I just replaced them one at a time making sure the wires were correct. Now sometimes when I put the key in the ignition I'll turn it on, dash board lights up, lights on, everything good. Then when I go to start the engine everything immediately cuts off. I go pop the trunk, jiggle the battery terminal wires, and it sparks by the battery terminals but then everything comes back on. There positive terminal had three wires, two thick ones and a smaller one. The smaller one was cut off and led to nothing so i'm starting to think that it may have been a ground.It was never there to begin with when I bought it and it didnt have this problem. In the picture you can see the little blue guy missing from that ground.
