It’s a 69. The resistor wire is in the dash harness. It is a milky grey color and actually has resistor printed faintly along its length. It is all obviously original. I unplugged the ignition switch and sent 12 volts through the resistor wire and got full voltage at the coil.
I wonder if a resistor wire can fail by not resisting rather than simply cracking and not transmit any power? Perhaps somewhere near the ignition switch the yellow wire (non resistor cranking ignition supply) is making contact with the resistor wire and allowing full voltage to reach the engine harness wire to the coil?
I’m thinking I might take a resistor wire from another old dash harness.and temporarily connect it instead of the original and see if that does the trick.
