Hey guys!
I problem with my car, been looking for solution but can't find any.

So the problem is, when i'm starting to accelerate a bit harder, there are coming weird noises from front right. Then i tried it with the hood open and i saw that with the noises comes also sparkles. It's from alternator area. I thought it might be problem with motor mount that the motor is mooving too much while accelerating and something is rubbing engine compartment. I've changed the motor mount but the problem is still happening.

Do you guys have any idea what it can be?

 

I would check all the usual things. Make sure the wires are on tight, especially the positive coming off the post on the back of the alternator. Make sure you are not missing any grounds. Check the wiring to be sure the insulation is not worn through due to improper routing. Also, consider the possibility that the alternator is just bad. Perhaps take it off and have it tested at the local parts store. It's usually free because they are hoping to sell you a new one. While you are in there, give the all pulleys a spin and a wiggle. If they are loose or the bearings sound/feel bad then that may be the issue.
