Ok, so this is now the second time its happened, after all the years we've owned the zed. For no particular reason the horn will turn on and consistently stay on until you hit the horn pad. It happened a few days ago, and once more just now while parked at work. My initial thought was that the interior temperatures got too high and subsequentially made the rubber horn pad expand enough for it to make contact with the horn switch plate. As it was fairly warm on that particular day, but far from the hot, hot days we experience here in Adelaide.... so go figure. But today, the cars in the sun but its far from warm inside the cab. Yet its turned on again. Whats peoples thoughts and opinions regarding this. Has it happened to you? If so what was your fix? Now that its happened a second time i plan on removing the pad and seeing whats going on. And try to resolve this potential ongoing issue. Till then, the windows are cracked and is seeming to help the situation. Feedback....GO!
Thanks! haha. Yeah im imagining its something like that. As thinking about it. The zeds pretty stiff on the road and we do have a dirt road to travel on at times. So it shakes the shit out of it at times. Possible somethings come loose. Shall have to inspect.
Reminds me of when the points died on my HR holden and the horn would go off every time I turned left, quite amusing.
Sounds like a wire shorting out somewhere. If I remember correct the power goes to the horn then via the button to earth (Z-electricians please correct if wrong) so any short of the return wire can set off the horn. I'd be looking for the horn wire rubbing on the chassis somewhere and has now worn through the insulation.
Thanks guys. Will inspect it over the weekend and report back. Im thinking the plates may be touching as to resolve the issue all i have to do is tap the horn pad. But its ultra sensitive. So somethings possibly come loose and its only a fine gap between contacts.
from memory, there is only one wire as the other one is simply grounded to the steering column. This pretty much makes it easy to short if there is any grounding of that one wire.
mine did this on my car and kept sounding the horn even when parked, replaced the relay not done it since, think the heat helped to expand things and just enough to cause the horn to go off.
