I just got my 65 running now the ignition won't turn the engine off. I figured out that when i turn the key to start the coil is hot but when i let off the key it gets turned off so i ran a wire from a switched source to the coil and now the key starts the engine but does not turn it off i have to unplug the battery in order to kill the engine. Any ideas on what i could to to make it so the key will turn the engine off?? Thanks

Have you modified / replace a fair amount of your wiring?

i tried to switch the wires on the starter selnoid and the starter does nothing so those aren't mixed up. I tied to run a wire from the stud comming out of the back of the ignition switch which is dead when the key is off and hooked it to the + side of the coil and it starts fine and will shut off the engine with the key but if it runs for more than a couple of seconds the key does nothing and i have to unplug the battery inorder to shut off the engine. Does anybody know what is wrong with this??? Thanks

That center post ties into the voltage regulator, which may be stuck. What's the voltage on the center pin when you turn the key and then remove it? It should be 0 Volts. If it isn't, then something is causing it to be hot, and that's your problem.

Are you sure you didn't tie into the center post of the cigarette lighter? That's hot all the time.
