HOT Wire
I have a 1982 F150 with 4.9l. I have an overheating wire. According to the schmatic it is the ballast resistor(red Lt green) very hot to the touch. I replaced the coil with a MSD coil part #8205 coil. I also plan on installing the MSD 6A electronic ignition. I called tech support at MSD and they said the coil should work ok with the Dura Spark ignition. If I remove the + wire from the coil the wire does not get hot. Any sugestions? Thanks Art

Maybe it is time to change out the resistor wire, or better yet replace it with a ballast resistor... my personal favorite solution
If you disconnect the coil + how does the truck keep running? Or does it? If it doesn't, and it shouldn't I would think, that is why it doesn't get hot no current flow thru it.
