Someone told me that there was a discussion on here dealing with flatheads overheating and they were sharing a simple idea of something you could bypass and you could buy what you needed at radio shack? Does anyone know what I am referring to and if so can you direct me to where I need to be?

The only discussion I can think of about bypassing something with something bought from Radio Shack is bypassing the coil resistor with a circuit using a diode from Radio Shack but that was about better starting in the cold weather, not overheating.

What I am looking for is a way to bypass and be able to crank the car when it gets hot like flatheads do. When it gets overheated it won't crank

just run a wire from one post of the resister to the other post-go thru an off/on switch and then use the switch to supply full voltage to the coil

Do you have a schematic to show me how? I thought it was something to do with a diode. What exactly is this suppose to do?

http://www.earlyfordv8.org/forum/fileattachments/Quick%20Start4.jpg Please take a look at this. This is what I have been told about, but I'm not sure how it will help when the car overheats and won't start. Help?

I believe this was posted by Superreal. I use it and it works

What size diode do you use?

I use the top hat type diode, which looks just like a top hat, it is aluminum and is a lttle smaller than a dime. I believe it was rated for 7 0r 8 volts and 20 plus amps. I got it from a Model A parts house. It'a used on old ford generators to replace the cutout. The switch that bypasses the resister will work just as well. I would use a push button switch. To answer your original qurstion: this sends full battery voltage to the coil momentarily while the engine is cranking.

I re-read your post more carefully. Your big problem is the overheating. I would find and correct the cause of that before doing anything else. As stated, the diode or resistor bypass will do nothing to correct this.
