When switching over to duraspark electronic ignition, do you run a wire from the starter solenoid to the positive side of the coil? From looking at some diagrams it looks like a hot wire runs up to the ignition switch and a wire from the switch comes back and attaches at one of the small posts on the starter solenoid. Then apparently it energizes the other small post on the solenoid, which is attached to the positive side of the coil with a wire. Does that sound right? I would think that would only give juice to the coil when key was turned though. I've also seen a diagram floating around where it looks like you can just splice the red and white wires from the elec. ignition module in with a switched 12V source and the wire running to the positive side of the coil. That really doesn't make a whole lot of sense to me though. Maybe I just need to run two separate hot wires, one to the positive side of the coil, and the other to the red and white wires from the electronic ignition.
The wiring harness for the duraspark is all self contained. In other words, all the components connect together through the harness. The only thing left over is the red and white wire off the module which I've always spliced together and hooked to a 12v source.
You're right, but I still don't know what to connect to the positive side of the coil. The wiring diagrams show it splicing into the main power wire running to the ignition module, but that doesn't seem right to me.
The factory resistor wire( red with green tracer) that connected to the coil on the points system still connects to the positive side of the coil in the duraspark system. Some people splice into this wire between the ignition switch and the resistor section of the wire to supply the 12v power to the red wire on the ignition box. I usually do this as close to the ignition switch as possible.
Look at the wiring diagram for the duraspark at Fletches mustang site www.jason.fletcher.net. Its a factory duraspark diagram, hope this helps.
If you have the harness, it will have a plug for the coil. You dont have to hook anything to it other than the plug.
