JohnD Posted June 24, 2016 Report Share Posted June 24, 2016 All, I'm sure that this problem has been discussed here, but I cannot find it. So has anyone any advice, please? Classicliffe mentioned in one thread that if the steering wheel hub contacts the shroud that surrounds the column, that could earth the circuit and sound them, but I cannot reproduce this by purposely putting a jumper lead across them. Nor does turning the wheel when stationary sound the horns. Any other ideas, tests etc, that could help me find the fault? I take out the "HORN TOP SPRING CONNECTOR" Pt No.142534 to disable the horns as otherwise it's so embarassing, but as we are off to Le Mans soon, I'd like to have them in use. Thanks, John Link to comment Share on other sites More sharing options...
Pete Lewis Posted June 24, 2016 Report Share Posted June 24, 2016 The cowl foul is a pretty std horn blower , but if theres a few mm gap it should be fine it has to be in this zone where the involuntory earth is taking over. Is the push actually breaking circuit Is there a gremlin iside the horn push , pete Link to comment Share on other sites More sharing options...
dougbgt6 Posted June 24, 2016 Report Share Posted June 24, 2016 The horn top spring connects to the copper covered disk, Rimmers 606462. On mine the copper was bent out a bit and touched the earthed body of the column when you yanked on the steering wheel. Link to comment Share on other sites More sharing options...
Dick Twitchen Posted June 25, 2016 Report Share Posted June 25, 2016 I, repeatedly, had the same problem as Doug and from a variety of suppliers, probably the same manufacturer. Had one that then worked for a year before also distorted, so gave up and fitted a stand alone red button a la kit car. Link to comment Share on other sites More sharing options...
dougbgt6 Posted June 25, 2016 Report Share Posted June 25, 2016 Sorry I should add that I bent the coper back in a bit and stopped the embarrassing random horn blasts, although, like Dick, It did start again a year or so later and has become an annual job.

JohnD Posted June 25, 2016 Author Report Share Posted June 25, 2016 Sorted, I think. I returned today to look at the problem, and now the horn sounds as soon as the ignition goes on. Tried a rubber disc, to insulate between the wheel boss and thre switch shroud. No effect. I have a Mountney wheel, with a horn button in the middle. Can't remember when or why, but I had modified it by adding a contact disc to the back of the button assembly, I think because the horn top spring contact didn't reach the boss, and then a piece of spring steel to contact the column nut. Again, can't remember why! But eventually worked out that of course the b******y steel spring shorts the circuit all the b*****y time, so the horn was doing the same. Removed the spring steel contact and normal service is resumed! The wheel boss was touching the shroud, causing intermittent sounding which the rubber disc sorts out, and my ill-advised spring steel jobbie was making it sound all the time. Test drive needed, but it's been sleeting rain. Tomorrow. Thanks for advice! John Link to comment Share on other sites More sharing options...
Andrew Posted July 3, 2016 Report Share Posted July 3, 2016 Hi John Had exactly the same problem when I changed my wheel all I did to resolve the issue was to loosen the collapsible steering joint and pull the wheel up couple of MM. to give clearance between the wheel boss and the column no more problems. Let me know your thoughts as would be interested Regards Andrew Link to comment Share on other sites More sharing options...
JohnD Posted July 3, 2016 Author Report Share Posted July 3, 2016 Andrew, The collapsing joint indeed limits up/down wheel movement if correctly adjusted. But my horn sounding on corners was down to the boss touching the column shroud, the covers all the wiring to the light/trafficator levers. A rubber disc, just larger than the boss/shroud diameter has cured that. I just wonder if worn column bushes are allowing more side-to-side movement than there should be, but it's sorted for now!

Guest Posted July 7, 2016 Report Share Posted July 7, 2016 Hello John. I have attached some photos which may or may not assist and these accompanied an article I wrote for a classic car club magazine. The steering wheel in the picture has a centre horn push and the original Vitesse horn contacts could not be used; hence I modified the set-up. The horn is much louder as well now, but that was probably down to the original contacts having carbon deposits / wear on it / them. The modification was done about 2x years ago and still going strong. Regards. Richard. Link to comment Share on other sites More sharing options...
Casper Posted July 7, 2016 Report Share Posted July 7, 2016 If I bought an expensive steering wheel boss for a Triumph (specify model) I would expect it to work properly with the usual equipment. I have modified a few cheapo steering wheel horn systems in the past, and fitting a dashboard button is the mark of a bodger. C. Link to comment Share on other sites More sharing options...
Guest Posted July 7, 2016 Report Share Posted July 7, 2016 Dashboard horn button, that's different !! Regards. Richard. Link to comment Share on other sites More sharing options...

barneygumble803 Posted July 8, 2016 Report Share Posted July 8, 2016 Hi, I too had this problem. Found out it was the indicator self-centering cam which was touching when I turned the wheel. Just knocked it down the shaft a few mm and it works fine. Stephen Link to comment Share on other sites More sharing options...
Dick Twitchen Posted July 12, 2016 Report Share Posted July 12, 2016 I could be offended if I was a wood turner, or the solution was done quickly/carelessly/without thought (definitions). Ten years ago the pencils were a recurring failure on the old forum, hopefully solved now the Club shop sells them; the correct sort of button seems to be a preferred solution among the Revival/Classic cars which are also road legal. In my case the horn push is only used twice a year (check and the MOT) as I much prefer hands on the wheel and driving technique a better solution to issues. The classic (sic) bodge was the Herald at Leatherhead being much admired which had 6 Scotchblocks in the engine bay and clearly not of a temporary nature. No response expected or required.
