Hi,
I have got a pair of Magnetti Marelli snail horns (marked T68 A 12v) which i think are correct for my Aurelia, and would like to fit them in place of the more modern plastic horns currently fitted. On applying power i can get one of the horns to work (it is the slave one with just one terminal) but i cannot get the other to operate/make any noise at all. I have cleaned both sets of contact points and tried adjusting the main contact which goes to the central coil, but nothing (although i can see it sparking across the gap). The outer contact at the bottom of the picture of the internals (which i think connect to the other slave horn) do move nicely on applying power. Any ideas on how to fix these - or does it need to go to a specialist- in which case any ideas there on who would be able to fix it?
Many thanks
David.
