Noise reducer on Alternator question.

[turbotalon1g]

So that little thing came on one of my alternators a while back, but I forgot how it hooks up and I don't want to risk blowing anything up.

I was wondering if anyone knew how it hooks up. I think the cable goes on the power side and the cylinder gets attached to the body of the alternator.

Any help is appreciated.

That must be what that lil threaded hole is for on the back of the alternator. Was trying to figure that out one day a while back... Never actually seen one of those on a dsm alternator.

I never have either and I'm 80-85% sure you are right, It came on a reman lifetime warrantied alternator a couple years back, so i just kept it. I remember that it made a difference with electrical noises in the car.

My old alty didn't have that part. The Reman did. Didn't feel/hear/see any difference. The dude at O'Reily told me it was for radio reception...wtf?

There are a bunch of them around the car I thought. I am pretty sure that it doesn't go to the power but it is just grounded out. I think there is one on the intake manifold bracket.

IMO I wouldn't put one on the alternator

He's right, those thingys are small capacitors, they filter out high frequency "noise" that the alternator generates, which can help with radio reception/ amp noise from your stereo/etc.
That being said, I've never had one on my dsm, and my current radio can pick up all the St. Cloud radio stations from my house in Coon Rapids, so I doubt it helps much.
