What happens when you hook jumper cables backwards?
Fuses (and/or fusible links) act as circuit protection devices between the battery and the vehicle’s electrical system. Connecting the jumper cables backwards will often result in one or more blown fuses. The affected circuit will not function correctly until the blown fuse is replaced.
