Answer
Hello Shay -

Can you tell me if that fuse blows right away, or it takes a while?

I am thinking the alternator either was put in incorrectly, or is the wrong one for that vehicle.

If you give me the part number for the alternator, brand name, and your vehicle information (year, make, model, and engine size) I will be more than happy to research for you if it is indeed the right one for your car.

Please get back to me -
thanks
