DTCHRISK Posted January 8, 2012 Posted January 8, 2012 Hello fellow strokers, does anyone know if a dodgy 6v horn is an mot failiure,as i can t get it to work properly! I ve restord the bike with a new battery and new horn,but it just does nt work!!! I know it could be converted to 12v but this surely isn t the answer? help
Moderator Airhead Posted January 8, 2012 Moderator Posted January 8, 2012 yes its a failure chris, clean the horn button contacts is what i would think
DTCHRISK Posted January 9, 2012 Author Posted January 9, 2012 everythings new, the switch the horn and the battery! when i put the indicators on whilst holding the brake,they flash alternately when it s ticking over.
KirriePete Posted January 9, 2012 Posted January 9, 2012 6v electrics are really sensitive to bad connections - let's face it, when you've only got 6v to start with, any loss is going to be bad. So .... check and clean all the connections (particularly earth points) you can get your hands on - a sheet of fine emery paper and a tub of Vaseline will be your closest companions for a while (maybe I should rephrase that? Naaahhh!) - even then don't expect miracles, 'rudimentary' is a good way of describing these electrics. Best of luck!
Paul Dawkins Posted January 9, 2012 Posted January 9, 2012 Defo an MOT failure mate The horn will need to be tested 5 times. Once on its own and then with each indicator then with lights on and then with stop lights on just to see if theres any interferance. Its a new thing. Go on ebay and purchase a battery horn for the MOT there about £8 but it needs to be continuos sounding and not a two tone. better still fix the one on the bike, therew cant be that much wrong with it. Are you testing it with the engine running? Some systems the horn and lights will not work without the engine running. Where are you in the UK ? If your down my way (Southampton) I can lend you a battery horn and MOT the bike for you
Moderator mervin Posted January 9, 2012 Moderator Posted January 9, 2012 just slacken the mounting bolts/nuts a bit, if it works then remove the bolts refit with loctite, leaving a little slack so they work, or rubber mount the horn
blackhat250 Posted January 9, 2012 Posted January 9, 2012 Ab merv says " and thers a nut in the centre of horn,, slacken or tighten, to adjust sound,,, or take it off connect it to spade connectors , then cross it over battery , if it works , then its earth or switch,,
Moderator Airhead Posted January 9, 2012 Moderator Posted January 9, 2012 There are two connections to the horn, one is 6v supply, the other is ground I suggest you eliminate or prove the horn itself... unplug the horn connections, wire one up direct to battery negative connect a flying lead to battery positive (dont allow the free end to touch your bike touch the free end to the other horn contact tab does it work? if it does then next prove the wiring connect the proper negative connection and repeat the flying lead positive wire test does it work if yes then the problem is in the supply from the battery, through the horn push to the horn if no the problem is in the negative return through to chassis and battery negative
DTCHRISK Posted January 10, 2012 Author Posted January 10, 2012 cheers fellows,i charged the battery up then tried it,and it worked as did the indicators...then ten minutes later they didn t . new battery i think!!
