Mercury Mariner Horn

The availability of the Mercury Mariner Horn gives a clear audible warning signal to the surrounding traffic. Thus, the driver can easily communicate its presence to other drivers and thereby avoid collisions. The system employs a steering wheel switch that transmits a current through a cable to an electromagnetic coil. This coil flexes a metal diaphragm which vibrates and releases a sharp blast. The original versions in Mercury came with a single-tone unit, while later Mercury models came with louder dual-tone units. These units couple two diaphragms at different pitches. This gives the Mariner a stronger reach in noisy streets. Both types of Horn maintain the same basic wiring and coil layout for familiar troubleshooting. A fading note indicates that the diaphragm is stretching, a raspy pitch indicates that it is cracking, and total silence generally means the cable or coil has stopped passing current. By making regular visual checks of the Horn housing and cable on every Mariner, drivers can catch these clues early. The Horn on any Mercury Mariner is a simple, yet essential circuit. A clean Horn that is tightly connected will work crisply and authoritatively.

We provide a wide range of Mercury Mariner Horn at the optimal prices. If you need Mercury Mariner Horn, you can shop with confidence on our website. All our OEM parts come with a manufacturer's warranty and are delivered to your doorstep with a fast delivery service.
