With the engine running you need to see around 10.5 volts at the coil + terminal when the charging system voltage is 14+. If you're running on a 12V battery without the charging system in operation the voltage at the coil needs to be around 9V.

Generator in place and spinning, but no wires running from it. Any recommendations on what or where for a resistor?

I just bought three to wire in parallel to make a voltage regulator setting resistor, for about $4.00 apiece.
