The car horn sits at the front of your car where grime, dust, oils, and other small particles can build up over time. This can lead to build up or corrosion on the connector, resulting in poor conductivity. Sometimes, all you need to do is clean the wire connector and reattach it (good ol’ WD-40 will do thee trick).
Connect one clamp to the terminal on the horn and quickly touch the other end to the positive battery terminal. If the fuse blows, you’ve got a bum horn.
