Description
This 18-inch single trumpet chrome air horn kit is built for 24V systems, including train, big truck, bus, boat, and tractor applications. It is a strong sound option for builders and enthusiasts who also shop for a ride on train setup.
Key Features
- Chrome-plated zinc trumpet: The chrome-plated zinc construction is non-rusting and designed to hold up across a range of temperatures.
- Powerful 150dB sound: The single trumpet produces a loud, attention-getting tone.
- Upgraded compressor: The red copper coil and vacuum chrome plating support quick response, so no separate air source is needed on the vehicle.
- Complete installation kit: Includes the horn, screws, nuts, pad, bracket, air pump, air hose, relay, harness, and fuse.
- Illustrated wiring instructions: A wiring guide with pictures helps simplify installation.
Compatibility
- Designed for 24V vehicles, including trucks, lorries, trains, buses, boats, vans, RVs, excavators, and ships.
- Not compatible with 12V vehicles.
Wiring Tips
- Horn and relay stay silent: If the horn does not sound and the relay does not click after wiring, the blue and white wires may be reversed. Connect them to the correct power sources, either the original vehicle horn line or the battery.
- Pump whines but horn is silent: The air pump's positive and negative terminals may be reversed. Insert the yellow wire into the positive terminal and the black wire into the negative terminal.
- Intermittent sound: Paint on the mounting surface where the black ground wire attaches can interrupt the negative connection. Attach the ground to bare metal at a solid power point for a stable tone.
