Klaxon is the uses often device when driving, if the horn appears breakdown, the meeting is very no-go when driving.
How do we see a horn first work. Should go up by next steering wheel or when the horn pushbutton of other position, the electric current that comes from accumulator can flow to the electromagnetism coil of horn relay through loop, electromagnetism coil attracts the contact switch of relay to close, electric current can shed horn point. Electric current makes the electro-magnet of horn interior works, make oscillatory film oscillatory thereby and sound.
In the breakdown of a lot of concerned horns, the breakdown of horn itself often is when occurrence problem. Especially the horn that certain car designs installs positional existence blemish, make very easily when rain horn by rainwater wringing, cause the damage of the horn. Can consult when occurrence breakdown the measure below is checked.
Do not ring sometimes by horn switch, if the horn rings sometimes, do not ring sometimes, the contact contact that is horn switch interior more is bad, some also are the problems of horn itself.
Because plug contact is undesirable,be more rustily, especially each contact all round steering wheel, because use frequent, make contact goes out to wear away now easily.
Do not ring completely to check frit silk to look above all whether fusing, unplug next next horn outlet, measure with avometer whether is there report here when pressing horn switch. If do not have report, should check horn wiring harness and horn relay; If have report, it is the problem of horn itself, also can try to adjust right now the adjustment on the horn nut looks to whether can phonate, if still be not noisy, need to change horn.
