Distributor contact?

[malik641]

I work at NAPA and the other day a guy asked me for a contact set for an 88 ford econoline 5.0L and I'm sitting there thinking "I thought a contact was for old ass ignition systems" so the guy explains how the ignition system sets out a high frequency the screws up the radio, so this contact makes sure the frequency doesn't interfere with the radio.
Now my mustang's radio screws up whenever i turn the blower on full blast or any accessory i turn on distorts the music just a little, but enough to piss me off. The radio works fine when i have the car off, and it sounds really good too.....So i tried to look for a contact and i couldnt find one.
Does anyone know anything about this contact? Any help is appreciated.

BTW, there was a contact set available and i did sell it to the customer, so this part does exist.

You might want to find a better ground for your radio. I have a small capasitor that came with the aftermarket harness and have no problems. I used to be big into stereos and found that the causes of that wine were either bad ground, bad wiring, or the need for capasitors.

90mustanggt is right. It's also why they use resistance wire in plug wires. It all prevents RFI noise.

yeah i guess ill just have to take it all apart again and find the problem

i have heard that it is that little plug next to the coil that keeps the radio noise out.
