i probed the light from pos. battery terminal to green wire terminal lead to coil: the light was on for 'Run" and then was definitely on (seemed to flash) while trying to start.

i believe this means the module is good.

i tested the spark from one of the plug wires yesterday and it seemed fine. Consistent and repeating spark.

The voltage before the coil resister reads @ 12v. The resistance of the resister reads @ 2 ohms. But the voltage after the resister (very hot, but won't do anymore) reads less than 1 volt. This doesn't seem good.

But the sparks are flying, and module is doing its thing. The coil resistance is primary about 3 ohms, secondary @ 9,000 ohms.

Suggestions welcome!
Assistance much appreciated.
