Radio, power steering, headlights, gauges turning off and on randomly while driving.

So I just wanted to add a thread here because when I was researching this there was little info about it (none on here that I saw).

So while I was driving every so often (usually when it was cold out) all the electronics in my car would start turning off and on if I say turned the wheel, or turned on the turn signal. It was very random and would not do it for months at a time.

I also had a weird electrical interference sound in my speakers that would change with the throttle / temperature.

The first time it happened I cleaned off my negative terminal (it had a bunch of fun green crust on it) and it seemed like it was fixed, but then a week ago it started back up. I checked the battery terminals and they were still nice and clean from when I cleaned them last year.

Then I checked all my grounds and battery with a multimeter and everything tested good and was nice and tight. So I bit the bullet and decided to change out the belt and alternator. Well it seems to have solved my issue and the high pitched noise is gone.

Just thought I'd put this out there to help anybody having the same issue.

Thanks!
