Could the wire harness be the cause of the alternator short out

 

PLEASE!!! Be more specific! What issues are you having with the car to think it's the alternator? A lot of people here are very knowledgeable and will help you but you have to put detail in your post to get a proper response pertaining to your issue. This tells us nothing.

 

I think I found the problem there's was some oil where the wire harness connects to the alternator

 

I'm currently replacing the alternator again but I'm going to have a professional work on the wire harness.I pretty damn sure I crossed up the wires

 

it never hurts to have a second pair of eyes check your work.

 

Agreed
