Xena, it's a '53 truck with a newer engine, if I'm following your thread correctly? The '53 would have been 6V, so no resistor wire or ballast resistor was required or used. You can either add a ballast resistor or change the coil for one with an internal resistor, if you don't want the resistor visible.
