Hi Erich,
I have a 12 volt horn similar to the Altette horns fitted to the Rubies. This works well enough on 6 volts to satisfy local (WOF/MOT) inspectors. It was not reliable for a while until I discovered that one cell in my 6 volt battery was faulty. With a new battery it's fine. This indicates that these horns have a high current draw, reinforcing John Cornforth's comment.
Regards
Graham
