As buckanddeere pointed out, you may not have had the correct ballast resistor. Additionally, when the engine is running, the dwell angle is the time the points are open (as I recall...been awhile) and it is on the order of 30% of the time. So the average power to the coil is 30% more than it is with the engine running. Couple that with the fact that the engine fan was not blowing any cooling air past it and the resistor, if installed at all may have been to small you have your problem. You might want to check your ballast resistor for overheating also. Course if it is too small, you will be replacing it anyway. txblu
