MG MGF Technical - Horn has packed up
|The Horn has packed up on my 53 plate TF. The fuse is ok because the windows still work and the horn works if connected direct to the battery> Any thoughts? My next guess is the contacts in the steering wheel but Im loathed to fiddle around the air bag. Has anyone else had this problem |
|The horn is operated either thru the rotory coupler or the Alarm.|
Set the alarm, open the boot and pull the bonnet lever. If the horn sounds, then it is the coupler circuit giving the problem.
|I had the same problem on my F'. I hadnt noticed that one had packed up a couple of years ago and all it was ...was that the horns had just "died". Replacing the two (quite cheap) from Sussex Classic Car Parts solved the problem.|
|Paul Carugati (MGF and MGBGT)|
|And there's indeed no option to repair a corroded horn.|
Prevent it from water ingress and bend the _trumpet-part_ downwards when installed.
|Roger Parker had a perfect solution to a non-operational horn. Whollop it with a wood-faced hammer, and then adjust the adjuster screw (if present - newer horns don't have them). This is usually all that's required, assuming this isn't a failure of the rotary coupler, which IMO is a rare problem. :o)|
|<the horn works if connected direct to the battery>!!!!|
suggests that it is a circuit problem.
|it's very common for the spade to pick up some corrosion, try running some emery cloth over the horn spade and up inside the one on the loom|
|If the horn does not sound on the alarm, then look for a problem between the relay and the horn.|
If the horn does sound, then look for a problem between the wheel horn buttons and the relay..
