No strands have been cut, but there is a 1" long slice in the insulation where it enters the engine compartment. If I leave the ignition on and go back to wiggle the wire at this point, I can hear the distributer "click", and the car will start right up. Instead of shortening and splicing into the wiring harnes, I was considering clearing the old insulation off, melting in some soder, and using heat shrink tubing to reinsulate. Is this too hokey? What's the best way to do this, I'm not too experienced. (Yet) Peter Parker '66 Square; Phillip Portland, OR
