Please, tell me where was the short in my car? The AC/rear wiper fuse blows when I put ignition on. Also, the 120ah fuse from the alternator and fuel pump fuse was blown.
The problem occurred, probably when my friend jump-started the battery from another car. Maybe he reversed the clamps negative to positive and vice versa.

Are the fuses still blowing? Or are they ok now that the battery is charged and fuses are replaced?

The only fuse that is blowing at this time, is the 10ah from the rear wiper, AC control module and radio unit. This occurs with ignition on. It must be a short circuit in the system. The other fuses are okay.

Disconnect all three units and see if fuse blows if not basic loom should be okay, plug in one unit at a time and see if the fuse blows, you may narrow down the problem circuit that way. My money will be on the A/C control unit as this will be more problematic with a crossed over battery.
