If you suspect an electrical issue with all this, checking for resistance in wiring is pointless if all strands are broken except one. When "Ohming out" wiring, it will test good, because it is checked without current flowing. The six volt side of the coil, grounds, and wiring to the distributor needs to be rechecked, because the most accurate way to check an electrical system is by performing a voltage drop test. When loading a circuit, that one last strand of wire inside the insulation will build resistance and impede voltage and amperage through the circuit with current flowing. Weak spark is an example, where voltage and amperage will drop, due to higher amounts of compiled or localized resistance. On a 12 volt system, voltage should not drop more than .2-.3 volts across a circuit. If it shows more, then there is high resistance. My assumption is that 6 volt systems would have a similar drop. I would check all wiring to and from the ignition switch, distributor, and coil to points, using voltage drop tests. You can also check drop across the grounds this way. Once you find it, overlay a wire, or jumper it to confirm. I hope this helps you out. Let us know.
