while riding home today, my bike died, lost spark. The coil split open and started spewing smoke like a boiling over tea kettle. It was so hot the plasic housing melted and dripped down the engine cases. It freaked me out for a minute, because i initally thought a gas line busted and started a fire on one of the cylinders. I turned the fuel off and jumped off the bike as quick as i could. When the smoke settled, I found what had happened. The bike is a 79 shovel with points ignition. Points are only a few months old, and this coil was checked when I installed it to make sure it was the right resistance coil for points ignition. My guess is that one of the high tension leads in the coil shorted out internally, as the ignition wires, and wiring for power and to the points are fine. Anyone else ever have this happen? Is there anything else I need to check? I believe the coil just went south, as it is a few years old and just a stock replacement HD coil, but am open to others suggestions and stories. Never hurts to ask, I may learn something new. Thanks, Chad.
