My ignition switch is B.O. so I have been attempting to install a push button switch to by-pass the key. I cut the black and red wire from ignition and soldered to create a hot wire to solenoid (tested12 V) and connected other side of switch to red fuse under dash. Turned key and started right up. However while checking coil for voltage while car was started I noticed black wire and clear resistor wire were not connected to coil. (During original tests Black wire from solenoid was 12 volts to coil and resistor wire was getting very hot.) I don't understand how car runs with positive side of coil unconnected. It seems all other electrical functions work O.K. at this point. Any ideas why this is happening? (Flame Thrower coil and standard points)
