Somebody put the battery inverse. The car is cranks but not start. The dash is not came on. Windows is not rolling. I checked all fuses look good. What else could it be?

Hello, I am Danny.

As a protective function, cars have a fusible link that fails for that reason to save the wiring system in case the battery is installed in reverse order like what happened to you. You will have to replace/repair the fusible link to get car to start. I have attached a tutorial and a picture of what it look like. It is mounted in the front left area under the hood. Hope this helps and feel free to ask any questions if needed. Thanks for using 2CarPros.
