Hi guys,
I have a high pitched buzz in my 89 Chevy pick-up radio speakers. It rises and falls with the engine rpms. I had the alternator rebuilt a while back but it didn't make any difference. Is there a suppressor in the alternator that the mechanic could have missed? Could it be something in the radio that is getting old and quit working?
It is not horribly bad, just an annoying high frequency whine. Even though I was married for 23 years, but I can't tolerate as much whining as I used to.
