My jeep quit running on the way home from work. When I pulled over I found that the stock wire for the coil had fried. It is the red wire with the white trace on it. I just did the TFI coil upgrade last weekend and today I fined that the wire insulation had melted and I guess it got hot enough that it just broke in two. Does anyone know what might have caused this? Anyone else had this problem after the TFI install? Any suggestion ion how to prevent it from happening again? Also when I got home and turned the key off I got run on and the engine would not stop until I seperated the two halves of the coil wire that fried.

I need to get my jeep back on the road by tomorrow so any help is greatly appreciated. I'm going to splice on a new piece of wire to fix it for right now but I need make sure that this won't happen again.

Thanks for all the help. als.

/wwwthreads_images/icons/shocked.gif I sort of sounds like you may have the red wire that connects from the coil to the solenoid on the wrong solenoid post. That's just a guess./wwwthreads_images/icons/crazy.gif

CJDAve I did nothing to the wire that is connected the the solenoid. All I did was remove the red wire from the plactic housing used for the stock coil and conneced to the connector I got from the junkyard for the TFI coil. I did notice upon further investigation that the wire for the coil and the wire to the solenoid both junction at the same point. In fact the wire to the solenoid also fried and it is connected to the right post.

Thanks for the help. als.

I had a similar problem with run-on after doing the TFI upgrade. If my idle was set high, roughly 800 to 1000 rpm, it would not stop when I turned the key off. I would get a bit of a miss but it would just keep on running, had to unplug coil to stop it. I set the idle lower and it worked ok.
