Rusty Alternator Ground ? Check This Out
After my alternator have been replaced in the shop I noticed a rusty piece of metal attached to it, which I don't think that it looked like that before.
Is this the alternator ground ?
Should I replace it or try to sand it ?

The alternator should ground through the case IIRC. At least this is how the one-wire alternators work. But the factory alt.s are not one wire, so I could be wrong.
That looks like a ground for something else...

I can't tell if that's the positive terminal of the alternator or just a grounding point, can you take a better picture? The positive terminal should have a rubber boot around it, and a pretty thick wire going back into the harness. If you have one handy, use a voltmeter between a known good ground, the negative terminal or one of the factory headlight grounds, and that post and see if there is a voltage difference with the engine running. Difference of 0.00, it's a ground, difference of 12.00-14.00 and it's the positive terminal.
Unless you're having electrical problems, I would leave it alone, give it a sanding if you're feeling adventurous. If you ARE having electrical problems, head down to the closest Auto Zone/O'Reilly's and have your alternator/battery tested. (But don't buy their alternators, go OEM)

I just wanna know if you guys have the same looking piece of metal attached to the alternator, because I think the mechanic did something wrong when he replaced the alternator.

I will try to clean the contacts on this thing and also the engine ground.

that's the alty to chassis ground.
I removed the bracket all together and ran 1G to the chassis(body).
the original wire is a 16G wire(thats the little black wire in your pic coming off the bracket, it runs just through the loom to a bolt right next to the washer resevoir.)

I'm also trying to ease the vibration as matrix11229 said.

Also what's the difference between 1G wire and 16G ?
Did you notice any difference after that ? (did you have any vibration before?)

nopike:
The chances of this ground having anything to do with your car vibrating are very slim.
