I fired up a new engine in my 65 today but encountered a problem with the wiring to the solenoid. Original wiring has 1 that went to the solenoid that is common with the + from the coil. The other wire(purple) which is the wire from the ignition switch. All worked fine last year with the 350. Anyways I now have a mini starter for the 400 so I was only going to use the purple from the ignition to the solenoid. My problem is that wire now has power when the ignition is in the on position same as the other wire. Is there some where in the system that could go faulty and provide power to the purple wire? I checked the ignition switch out and it is fine.
