Kelly - Sometimes, especially in cold weather, engines can have trouble starting because cranking voltage can be as low as 9 or 10 volts. If ignition voltage is being further reduced by resistors ahead of the coil it is possible that insufficient voltage will be available to fire the coil. The remedy? Bypass the coil resistor during the cranking cycle by running a wire from solenoid "R" which is activated only when cranking. Once the key (or button) is released "R" goes dead and the coil must draw thru the resistors.
