High Pitched Noise

[TeamST_racing]

It never happend before the swap...

But after the swap, eveytime I step on the car or idling, the radio makes this weird Winding high pitched noise. It makes it hard to listen to the radio.

What do I do to solve this? I have a stock Head unit btw.

Does It Get Worse Whne U Hit The Gas?

sounds like alternator whine. Does the pitch go up when you rev the motor?

Interference.

You dont have an AMP installed do you?
Probably not on a stock head unit...

Check your coil & dist. setup...see if it's off...

the alternator squeel solely comes from the alternator bearing...so that's not it.

Could be ground noise. Recheck your grounds i would say.

Yeah... i was thinking ground noise as well. Check grounds... or look into buying a ground-loop signal isolator. They can work miracles.
