Morning chums, wondering if anyone can help me out here. Usual pair of voxbells, had the grilles re chromed last year ( C.E.D. excellent) since then whenever I'm out for a spin I'm getting rather feeble horns. At rest they are exceedingly loud but once under way it's a different story. The little return spring on the horn button has given up the ghost so I've shortened a ball point jobby to fit. I've cleaned the switch out several times. Also put new spade connectors for the horn connections. The earth wire from the switch body is ok.I don't have any spares to try so I'm a bit stuck. Any ideas? Many thanks .Stuart. PS I'm on nights at the moment so if I don't reply during daylight hours it's because I'm unconscious!
