Thread: What the hell happened inside my distributor? Pictures inside

Tweet

So I thought I had a carbuerator issue because the it didnt sound like a miss, and it drove fine at a higher RPM. Then I pull the distributor cap and find this. This is a Mallory 2092M distributor with vacuum advance.


So what I found was the center point underneath the where the coil wire comes in was completely burnt off, and the one side of the distributor cap has a giant gash in the side of it. Im guessing maybe an arc from a shorted wire? I have new wires that were just put on, and new plugs as well. Do you think it could have possibly taken anything else out in the ignition?

I need to add, when this problem started I found a plug wire had vibrated loose and was not connected to the plug. Upon pulling the wires i found the boots to be resting against the exhaust because they are incorrect wires, it could have possibly arced.

Im hoping this solves the issue. I had another post in the forum elsewhere but I took a break from the truck so that I didnt go spending money on something that wasnt an issue. Its good I did take that fresh look.
