Relay on horns

[Demetris]

Regarding the horns, if the respective fuse is intact, you may find that the stalk switch has burned its contacts.
It's not too uncommon as the horns use quite a bit of current. A cleaning of the contacts will restore function, but in the long term i have found that the fitment of a relay was the permanent solution.

hi I was about to suggest the stalk but didn't know the cause so I have learnt something!! thanks.... may I ask how u fitted the relay?
many thanks

You only need a single relay that you will bolt in a convenient place, i.e. to the front of the inner wing.
You feed the relay using a fused line that is permanent live. In my case (series 1) i connected it to the unfused side of the fuse box because it was easy. The fuse box is bolted on the front inner wing. Don't forget to add an inline fuse between the source and the relay.
The original line to the horns will be used to switch on the relay, while you also have to connect the relay output to the horns. Finally, don't forget to earth the relay.
Please note that the relay feed and output wires should be substancial (i.e. 2,5) while all joints should be properly soldered and insulated.

I think that i used at least a 30A rated one.
I always tend to use high rated relays as they are more reliable and the price difference isn't that much.

The horns use about 5 amps each.
