horn

sorry i couldnt post this in the electrical section.
all i get when i press the horn button is a click from the relay i,ve got power to the horn but no horn noise. is the horn bust or could there be something else wrong? (before i go and get a new horn)

Make sure it has a good earth, poor earth could be enough to trigger the relay but not carry the current off.
Easy way to eliminate a faulty horn it to run 12v straight through it, if it's working you'll probably be deaf after

If the set up is twin horns connect just one and try again .

PARDON?

Typically twin horns will just pip when you hear the relay.  If this is the case and a direct 12v feed makes them blare then the wiring is old and can't deliver the power.

In this case you have three options - fit a single horn, replace the old wiring, use a second relay in the engine bay to operate the twin horns.

thanks everyone it is twin horn so i,ll try connecting one 1st. have to be on the weekend though as it is still dark when i finish work  

horn working again now  i ended up running a wire straight from the battery live to the horn and it works  m.o.t on friday. fingers crossed. its been off the road for almost 4 years
