Question what does the capacitor do exactly?

Hello

doing some clean up on my truck -1989,5.0,std,4x4-

I noticed the wire to the capacitor (next to the coil) was frayed

what does that capacitor do?, and would the wire being frayed affect the performance of the truck?

this is a 200.00 plow truck..so I am still sorting out stuff trying to get it to run right

It keeps Ignition noise out of the Radio.

If it touches ground it would burn out a fuse link and the engine would stop. Other than that no it would not affect the performance.

It's a storage center for electricity.....Thus, its name

Those little suckers have the capacity to store thousands of volts.

The spark that doesn't go to the spark plugs gets arrested to the condensor/choke/capacitor.

Not the ones in our trucks, that much voltage would arc through the foil of a Radio noise capacitor.

Not true, the spark has nothing to do with the Radio noise capacitor.
A choke is a coil of wire and does a different job than a capacitor.
The name was changed from condenser to capacitor in 1922, before that they thought that it condensed the electricity away.
