Thanks for all the info. We did observe a spark, although it may be weak. Now, I have to find TDC again, we tinkered around with the dizzy location with little or no improvement.
It's really frustrating. This thing would start and purr like a kitten when I got it. But it had no brakes and the shocks were shot. So road travel was not happening. I finally get the brakes rebuilt and installed new shocks..No go..
I'll try a 2 battery approach this weekend. Judging by the responses here, the stock coil does not use a resistor and get's a full 12v.
