What I found was a bare wire on the brown wire------such that when I pushed the column in it would push that bare spot up against the tube---closing the circuit and blowing the horn. All is well now.</div><div><br data-mce-bogus="1"></div><div>The task is a pain but really not too bad. I had to cut three of the bullets off, wrap the wire with a piece of wire and pill it thru. then reattach the bullets. (you do need another hand up above to guide it into the inner tube). </div><div><br data-mce-bogus="1"></div><div> I use the Flan air horns and they use a relay---I had forgotten I had a horn relay installed and couldn't figure out why I got a click but no horn when I hooked it all back up and tried to blow the horn-------short answer--the relay had quit. New relay--all is well.</div><div><br data-mce-bogus="1"></div><div>If you ever do this job remember that two of the 4 wire attachment posts are "floating" posts and will fall out when you remove the wire if you don't block them from behind--and THIS is bad news-----------you either spend tons of time trying tore-insert them ( using a flat small object or you take the trafficator apart in order to get them back in---not what you want to do.</div><div><br data-mce-bogus="1"></div><div>Thankfully mine is back together and working nicely.</div><div>Tom</div></body></html>
