roasting coil wire

thanks guys! i think i figured out most of the problem, i still need to measure the resistance through the wires, but i have a bad feeling my blaster SS was on its way out for a while now. fired it off this morning when it was cold, and i could hear the arching much more, everytime id blip the throttle it would do it. I have a hunch this is how it played out, the coil was failing in its di-electric properties, stressed the coil wire, coil wire turned to powder, blew itself apart, and the coil had nowhere to dump its energy, so it blew the side out. I could see the coil sparking nice and blue straight into the firewall, and i could see that messing with my tach, since my old autometer units (i have 2) seem to be extremely sensitive to electrical faults. My crimp on the faulty coil wire wasnt as sufficient as id like it to be i noticed, it wasnt fully seated in the tower, so i made sure my new wire would fully seat on the tower, i dont get though that it took 2 years for this to happen, and the tower in the cap wasnt damaged at all. reguardless it couldnt have been helping the situation. I was reading MSD tech sheets all last night and they recommend using a spiral core wire, im not, im just using straight graphite. however i have been for 7+ years on 3 diferent rigs and this is the first problem ive ever had. fired up the truck after replacing the coil and its just like it always used to be, the only difference i noticed was the exhaust isnt nearly as "raunchy" as it was last night, makes sense, faulty ignition coil, unburned fuel and so on...so time to ohm out the wires!!! then possibly build myself a set of spiral core units. thanks again guys!
