One time I had a customer that had the same symptoms on his D-17. He had replaced the coil, so right off I thought I had found the problem (I thought the coil was missing the ballast resister) and replaced it with the correct coil. WRONG, the problem was still there. 3 service calls later and after much reading and study, I came up with the cure. Voltage regulator was putting out too high voltage causing a chain reaction clear to the points and plugs. I replaced the regulator and all damaged parts and no more problem. I suggest you check the voltage regulator output. Duey

Some aftermarket replacement coils do have a resistor built inside the coil and some do not. It greatly depends on the application and system the coil is designed for. Usually on the outside of the coil (when it's new) it will say whether it should be used with or without an external resistor. Unfortunetely, if it's an old coil, it may be worn off because it's usually silk screened on the coil in ink by the manufacturer who made it, and therefore it would be unknown unless the coil has a P/N on it somewhere to identify it. As for your burning up ignition parts, that could be either high or low voltage being the culprit. Hope this helps a little...
