Hot Wire

Started my CJ7 258 with nutter bypass after putting it together from PO. Don't know if wire colors are original but I'll try to explain. The wire that goes from the I terminal on the ignition relay to the solenoid also has a Red wire that goes to the constant "Run" power connection when Jeep is started. It connects to a group of yellow wires also. The problem is JUST this Red wire gets warm. NOT the wires that its connected to. Green wire off of relay and yellow wires that go to the fuse box and wire that goes to solenoid all stay cool. What's up with this??? Thanks for any help I could get.

Good news, its normal and working properly.


It's the resistance wire to the coil that drops the power to the coil. Since its a resistance wire, it gets warm. If you put in a high output coil that had a lower resistance primary winding, then the wire gets hotter.

If you are running the stock ignition system, you need this wire or do a stealth HEI setup. If you are putting in an HEI style distributor, you can remove this wire and put in a regular wire.

Without this resistance wire, you will be burning up ICM's.

Should this be a special type of wire or do you use a regular wire? I don't know what the PO changed under the hood.

Yes it's a special type of wire.
It's a resistance wire.
About 1.34 ohms for that length.
You could use a ballast resistor in place of it.

it starts at this splice and goes to your coil

Unless your PO made some modifications.


If you use regular wire you could burn up your coil or ICM.

That looks like it but the other wire going to the ignition module is a thinner green wire. What size wire should that be? The wire going to ignition switch is heavier but yellow. I'm assuming that's a regular wire also???
