Re: COPO Chevelle start/run problems
The little yellow wire that runs from the solenoid powers the ignition when the key and switch are in the start position. When you release the key, you would be running on the normal ignition switch and the resistor wire running through the rest of the harness. If the ignition switch or the resistor wire is at fault, it could start or run in the start position, but not in the run position.

Re: COPO Chevelle start/run problems
When troubleshooting a no run condition , I always start with a test light at the coil + terminal. With the ignition in RUN position there should be 12 Volts at the + terminal . If no voltage there go to the 12 ga purple wire on the Ign switch and test . If you have power there ,find the open between the two places you just tested . If no power at the switch ,adjust the switch first ,if still no power replace the switch.

Re: COPO Chevelle start/run problems
Purple wire just energizes the solenoid. It does have to go through the neutral safety switch first though. It doesn't really have anything to do with the actual ignition circuit.

Re: COPO Chevelle start/run problems
The power to the ignition is overrode from the starter solenoid. It then gets full battery voltage as opposed to resisted voltage.
Different circut, thus different results. Tim |

Re: COPO Chevelle start/run problems
Thanks guys. So, ...... + side of coil had 10 volts in the start position, but 0 volts in the run position. Put a wire from + battery direct to + coil and started right up and ran. Looks like the wiring harness (resister wire) is no good as predicted by you folks. New wiring harness on the way!
Thanks to all the responded! Peter
