I have a 69 and a 70 and both have this thing about the size of an AA battery that has a wire going to the voltage regulater. What does this thing do? The one on my 69 is loose and the guts are spilling out of it. I haven't messed with it cause she's running fine. Should I replace it or can I get rid of it? I need to know what it is called at least so I can order it. I was thinking it is some kind of resistor for radio noise.. ??

It's the radio suppressor. It's suppossed to keep the radio antenna from picking up line noise. Don't ask me how it works, though *LOL*.

It's a capacitor - in electronic circuits caps are used to filter out unwanted "noise".

IIRC capacitors don't conduct DC but do conduct AC - so our battery DC circuit is unaffected.

Did that make sense? Is there an electronics Engineer in the house?

Unless there's been some recent developments that I'm unaware of (that'd be no big surprise) they are not made in reproduction ... you have to locate a used one.

as a previous poster stated it is a capacitor connected from 12V powaer to grd which provides a short circuit to AC current and a high impedence to DC current so that alt switching noise (caused by rectifying diodes) and relay switching in VR AC gets shorted to gnd and does not get into radio - short is not perfect so some can be heard if cap is old.

Get yourself a small capacitor and hook up the positive end to your positive terminal on the coil, then hook up the negative end to ground. It will serve the same purpose (you can use a valve cover bolt if you clear the paint off from under the bolt head).
