My Electrical Woes Continue

To review my recent problems, I managed to blow out 3 Pertronix ignition modules before I learned from the Pertronix folks that the new Pertronix coil I had (a Flamethrower II) was not compatible with the basic Pertronix ignition module that I was using. OK, so I ordered a new module and a new Pertronix Flamethrower (not a II) coil. They arrived today. I installed the module and the coil and the car (it's a '67 coup with a 302) fired right up. I was delighted! Well, about 5 minutes later the wire from the coil to the distributor blew right out of the distributor and the engine (of course) died. I checked the cap of the wire and it was extremely hot at the distributor end. I changed the distributor cap, fired up the engine and kept my hand on the cap of the wire at the distributor and it again got very hot so I shut the thing down. I changed the voltage regulator ( I have lots of spare parts) and the engine fired up but the wire got hot again so I shut down once more. My question is - what can cause this wire to get that hot? Sorry for the long dissertation but I wanted to cover all of the points. Any help will be appreciated. E.
