threehundred Posted July 18, 2014 Share Posted July 18, 2014 took my Glanza in for it's MOT today and I've hit a few problems already... 1) the horn hasn't been working for a while, I pre-warned the guy about it, he's had a look but can't find the problem.2) my back number plate fell off driving to the garage today, I need a replacement (smaller square rear plate) asap but can't find anyone in Southend area who does them3) the doesn't have a rear fog, he can't pass it without one. What are my options? horn - any suggestions? is it a common problem?plate - anyone know anywhere in southend/Essex or online who can make me a plate quickly?fog - does it REALLY need one or should it take it elsewhere? Thanks people. Quote Link to post Share on other sites
Turbo Goose Posted July 18, 2014 Share Posted July 18, 2014 Do you have a multimeter? Quote Link to post Share on other sites
Socks Posted July 18, 2014 Share Posted July 18, 2014 Horn could be a few things... 1, the wires cane snap off the connectors due to age.. Glanzas have 2 horns so unlikely both have failed... 2, Fuse? Foglight. Majority of owners wire a light up switch into one of the 4 rear lights on the back of a starlet turbo... So much better if your friendly with a tester tho ;) Quote Link to post Share on other sites
Turbo Goose Posted July 18, 2014 Share Posted July 18, 2014 If you have a multimeter/ voltmeter. I would take the horn button off and check you have a 12v supply to it by putting one probe to earth (a bolt on the door hinge or something) and the other to one of the incoming horn wires. One should show 12v.if you have 12v here, go to the horn unplug the wire from it and do same again with someone pressing the horn ( one probe to earth and the other on the horn wire) again 12v should show.If theres not 12v to horn button, you know theres a break in the supply.If theres 12v at horn button but not to horn itself ( with horn pressed) there is either a break in circuit from horn button to horn or the button itself its knackered.If theres a supply of 12v all way through to horn when horn is pressed you know horn is kaput.To check horn button is functioning. Set multimeter to ohms (resistance) and put the probes to the terminals on the back of button itself with horn unplugged. The resistance should be high when horn button is not pressed and very low when horn button is pressed. Quote Link to post Share on other sites
