For the JCB machines: horn 704/37300, a genuine JCB part. The card also lists 335/B4669, 401/L8899.

The horn is held to its bracket by a single bolt, and its sound outlet should face down or sideways so water and mud do not collect inside. If the horn earths through its body, the bracket face must be clean, otherwise it sounds weak. According to sources, the numbers 704/37300, 335/B4669 and 401/L8899 are used for the same horn. The horn is chosen by voltage and connection type. After the change, press the button to check the sound. The horn's tone adjusting screw is set at the factory and is not touched. The horn's wire joints are covered with a protective cap against wash water. If the horn is silent but the relay clicks, the fault is in the horn or its earth; if the relay does not click either, check the button or fuse. The horn comes new.

Fitting

After fitting, secure the harness with ties so it does not touch moving parts or hot surfaces, since a chafed wire loses its insulation and causes a short circuit.
