Hei conversion Intermittent start?

That's a good call on the ballast connections Del. Thank you

What I did with my own system is use both "run" and "start" wires of the ballast connected together for my ignition power source to the coil.

Magnumdust, did you have a four wire ballast?

One really easy test would be to run the coil positive wire direct to the battery.
It should fire right up this way also.
