Today I was trying to get rid of a squeaking belt on my car. I didn’t disconnect the battery before I started working. I know now that that is an issue. That being said I accidentally touch the alternator positive terminal to a metal portion of the alternator. It caused a spark. Now my car won’t start. No crank no clicking.What can I do now? Do I need a new alternator? Do I need a new positive wire?

There is a 120 amp fusible link which sounds like has blown out which is normal to protect the system. here is a alternator wiring diagram so you can see how the system works with the fusible location so you can check it out. (QR)
