Ballast Resistor vs. Resistor Wire - 67 250

[67farmtruck]

=Can't be the points or condensor, can it? I have super low voltage at the + wire to my coil when it's disconnected from the coil. Points and condensor aren't even in that circuit, are they?

Seems like it must be either the ignition wiring or the switch. So I can run a wire from the unfused spot on the panel to the + on the coil with a ceramic ballast inline to bypass my wiring harness?

Appreciate all the insight and knowledge of you all.
