Re: Smoking Ignition Wires….Exciting stuff!

I don't have a '59 GMC wiring diagram at my disposal so I have no idea what circuit those burned wires serve. I doubt if the HEI distributor is the source, only a victim of the "fallout".. Power wire feeding the distributor should be at least a 14 gauge wire, preferably a 12 gauge.. Do away with the ballast resistor, it's jumper, and associated "light duty" wiring. .

As bad as those wires are burned, I'd think something is shorted directly to ground. IF that purple wire is designed to activate the starter solenoid and you have a foot operated starter, I'd start there.. A burned wire is easy to track down -- just follow it from end to end.. One end will be the power source and the other end (where the burning stops) is the source of the short... Fuses, fusible links and circuit breakers are designed to protect wiring from this sort of damage. Your truck has none of these safety devices -- get that corrected ASAP...
