I have a 1994mine Chevy s10 blazer with a built 4.3 l w motor engine.my problem is I put my msd pro billet distributor back In it.I also have a msd GM blaster coil hooked up to it. I've melted 3 cap and rotors just on the in coil contact point but this only happens when my running advance wire under the passenger side dash is connected. If its disconnected it runs fine I'm at a loss plz any suggestions.
