R.Wyant,
I think you want a "weak" spark "at the points"...this is the primary side of the ignition, not the "blue spark" secondary side. If this is a 12 volt system with no resistor wire or ceramic start/run resistor to the primary (key) side of the coil, I would expect 12 volts with key turned on. I might not understand what you are asking!
Stuart.
