wiring horn

[let_nova]

have my mot the day and my horn is not working. i have a momo steering wheel but the horn button does not work. could someone please tell me of an alternative.

Take the horn button off and check the wire behind it.

Also check the fuse, but its the same one as the windscreen wipers, so if they're working that'll be ok.

theres only the brown/white trace wire going to the steering column. cant find a live?

Theres two wires, one is connected behind the stalks, and iirc the other is a earth? Cant remember how the nova horn is.

has the horn ever worked as it sounds like the plastic bit you remove off your old wheel and fit to the momo boss hasnt been fitted.

My horn stopped working after i put gsi steering wheel on. all wiring/fuses were fine, the problem was a pin behind the steerng column that had disconnected. take off the plastic steering surround thingie and look to see if that pin is connectd - should be a wire going into it iirc. that sorted my horn prob. also, does your horn ever go off occasionally while your driving along?

The wire going to the column is the +ve, and the shaft and column acts as the earth IIRC. Check it's connected and that you're getting 12v through it.

The 12v wire connects to a sprung pin that touches the contact ring of the steering wheel. A wire comes off the contact ring to connect to the horn push. The other horn push wire connects somewhere to the column to ground it.

on the back of your horn push do you have two wires

one goes to live (there should be a wire coming coming from the steering wheel boss ) thats the live wire connect it to live on the horn push

fit an eyelet connector to the other wire on the horn push drill a small hole inside the boss use a self tapping screw to secure the wire
the horn should now work
