Condencer On Coil ?? (ANSWERED)

[Gold Rush]

I've been working toward putting my '74 SE together a couple years now. This one thing keeps eating at me every time I notice it. I don't recall ever seeing a condenser mounted on the coil bracket and attached to the positive primary post. I can't find anywhere in the shop manual making reference to this being OEM.

Anyone have insight you'd like to share??

All i can say is put it there,if you like to listen to your tunes fuzzy free.

I agree. Noise suppressor.

Yes, it is a radio noise suppressor. For AM radio only. FM by design eliminates that particular source of noise, therefore the capacitor is not needed on FM systems.

Don't know if the suppressor was still a factory installed item in '74. Your FSM would have that information. If not, then it was probably eliminated by '74.

THANKS for the INFO

I went to my FSM and sure enough there are actually three "capacitors" for NOISE SUPPRESSION. One internal to the alternator attached to the output stud, one on the back of the instrument panel attached to voltage limiter input, and the third one is the condenser I asked about.

I would have never thought about radio interference!!

interesting i had noise on my FM put that little capacitor back in no noise now.

Yes, there are 3 located as close to the sources of the noise interference as possible, alternator, coil, and voltage limiter. So, they were still using all of them in '74, wasn't sure of that. Good to know! Thanks.
