Good day, I connected the positive terminal battery to negative terminal. What are the damages that can be affected and can I locate them? The vehicle can start. Thanks.

Unfortunately, when this happens there is not always the same thing that happens. It depends on how long they were connected and what modules this vehicle has. So what happens is when you send the current through the ground side of the vehicle it passes through the modules or component first and not through the fuse first. So if there is too much current the module or component is going to fail before the fuse.

So we need to check the operation of everything and find out what does not work. Then we can figure out what needs to be done.

We would start with checking the fuses for this because hopefully the module stayed intact and the fuse just failed. Here is a guide that will help with this:

Let us know what is not working and we can go from there but I also attached the fuse information below. Thanks
