<VV> [FC] Cause of Bad Ignition Switch?????

Your problem is in the resistor wire in the coil circuit. When you are in the start position, you are bypassing the resistor wire and giving full battery voltage to the coil. As soon as you let the key go from the start position to the run position, you're running on the circuit with the resistor wire. The resistor wire isn't providing any voltage to the coil.

Subject: [FC] Cause of Bad Ignition Switch?????
I am posting this on VV & Corvantics as I don't know that it is really truck unique. My brother's 61 Rampside seems to have an ignition switch or wiring problem. His truck suddenly wouldn't run after starting in the start position. As soon as the engine started and you turned the ignition switch from start to run it would quit. If you hot wired the coil it would stay running. He bought another ignition switch which came with its' own key. He swapped lock cylinders to keep his old key. When he turned the key to start it the switch started smoking. We took the old lock cylinder out and put in the one that came with it back in. It started and ran fine. Problem solved we thought. We ran it long enough to adjust the carbs and then shut it off to make a few last choke adjustments. When we went to restart it guess what? It would not stay running. Same thing, dead once off of start position. I went to hot wire the coil and in my tired state put the lead on the wrong side of the coil. I think I fried his electronic ignition as it will not start at all (no spark). I was looking at the wiring diagram and see one for the ignition switch in start but not in run. What is the source of power to the coil in the run position. What should I be looking for?
