Radio supressor/Capacitor/Ignition Condenser

Ordered a new Capacitor/condenser. I was told by many (& have seen this on a few forums) that the little black box that goes to the + side of the coil was to prevent radio noise. It is in fact an ignition condenser. It is in the wiring schematic in the Haynes manual. I have heard many of you say your truck runs fine without this connected. But I have heard a few say that they have sluggish power & misfires with out it. My plug wires say "Radio Suppression" too...Does that mean they are there to keep my radio reception clear? I don't think so. I do however appreciate all of the tips & advice. You all have helped me go from a non-running truck to a yard driver. Dying to get it on the road, but at least I can move it in the yard.

From what i understand its to keep electrical noise out of your radio. I havent haf to mess with mine but thats the understanding i get of what its for.

I had apparently broken the little wire to mine, had dug down and re-soldered the wire into the nub.

A few years later I just bought a generic one for an old VW at the VW parts store. I still don't know if that did anything, think it maybe is for "AM Radio".

I have seen there are two possible condensers like this in Mazda trucks. Depending on the model year one is for the radio and one for the ignition.

I've seen some members report there are ignition issues when they don't have the one mounted on the distributor. Dan
