I just got my wildcat wired up and cranking but i noticed my coil is getting really hot just in a few minutes. Not sure why or if thats normal
Do you have a factory resistance wire from the switch to the coil? It should be, I think, black and pink, and step the running voltage down to +-9 volts. (You crank on 12 volts from the starter but run on less). If a previous mechanic ran non-resistor wire from the switch to the coil, you’ll need a ballast resistor (like Mopars) in the line to step down the voltage. If you don’t, the coil will last 30 days and fail with the bottom pooched out. Ask me how I know! (I don’t know if that makes it hot while It’s dying but I’d think it would). Patrick
So I'd say not. The wire is red maybe im color blind. That wire is tapped right to the yellow wire which is hooked up to the starter as the picture. Note is possible i got the yellow and blueish wire backward but car runs so i doubt it? Also that's a older picture before i connected the battery which is connected right with that red wire on the solenoid
I Think that’s the ‘crank’ wire, which is only energized when starting and should be 12volts. The ‘run’ wire (resistance) goes straight from the ignition switch to the coil (not the starter) and should step down the voltage.

What are you trying to fix? I don't see a problem except that you're asking why your coil is getting hot. It will be hot to the touch normally. Shouldn't fry an egg, but it will be pretty warm.
You need to check your voltage to the coil with the switch ‘on’. If it’s 12 or more volts that might be causing your heat. The wires you show to and from the starter don’t supply power during ‘run’. Patrick
Honestly just what is really Hot..... Coffee cup hot?= With hot coffee in it of course.. Radiator hot? = With engine at operation temp... In other words running at least 45min.... Exhaust manifold hot= Same as above... Do you have a infrared temp gun?
Just for starters the coil could just be shot.... With the key on (NO MOTOR RUNNING). what's your voltage on the pos + of the coil.... Should be about 9ISH... Ohm read your coil.... Lots of info on the web,,, YouTube,, on testing coils...
In the mean you need to check your plugs, wires, cap, rotor, points, ( gap & dwell ) condenser..... I've heard a sloppy timing chain can mess with the ignition...
