You have to consider that this was in the late 50's when I had one

Hi Will,
Back in the fifties, all the high end General Motors cars used a
little spiral spring thingie in the wheel bearing cap to ground the
drum, for less AM interference.

Re: Eliminating Niose on Ham Radio Jeep TJ?
 

Not exactly the same problem, or discussion, but can you guys comment on the
installation of a ground loop isolator to reduce noise in car radio?

Does it go in the b+ line ?? At the radio, or at the battery ??

Thanks !!
