The coil is designed to operate with no resistor, neither external nor inside the case. The windings of the coil are designed to operate well with charging voltage while running. Coils operate, when the engine is running, about 50% of the time. This is the amount of time the points are closed, compared to when they are open. Though the on off cycle is at engine speed, the effect is to limit the "on" time. the coil is not intended to stay on. If while you were testing the system, the ignition was on for even 3 or 4 minutes, it will begin to heat up. Engines tend to stop with the points closed because of the compression strokes and unused power strokes positioning the pistons just so. Putting a test light on the distributor side of the coil and cranking the engine with the ignition on should show a flashing of the test light as the points open and close. Assuming the light never flashes, and that the wire from coil to the distributor is in the open and good, the distributor connection through bolt, or the points and or condenser, are shorted to ground. With a plastic knife from fast food, or a piece of plastic cut from a milk jug, placed between the points, see if the battery voltage is now at the coil- If not, My guess is the insulation washers where the pass through bolt is located is ut of place allowing the bolt to touch the housing.

Unless you are from another planet, physically or otherwise, I don’t think our internal combustion buddies will talk and tell us their problems. But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
