There should be a resistor or resistor wire in the circuit to step down the voltage from 12 to 14 volts to 6 to 8 volts. Running it too long that way will also burn up the ignition coil. HTH. - Jim

I hope you aren't running a hot wire through the points, the points are a condensing ground circuit, you can burn out points and condenser that way. The only hot wire is on the ignition coil and it will have gone through a ballast resistor so it is not battery voltage.

Since you have no power to the coil, check for power at the ignition switch. If you have power to the ignition switch but none coming out, ignition switch is bad. If you have power coming out of the ignition switch but it gets lost going to the coil, the wire going from the ignition switch to the coil is bad. If you have no power at the ignition switch check the wiring down by the starter. There may be a burned out fuseable link there. HTH. - Jim
