Busina straight tap to battery, nagloko, how to fix?

[dr. d]

Yung after market ko na busina nung pinakabit ko sya around 10 years ago eh direct tap sa battery.

Nagloloko sya ngayon. Pag busina mo hindi tumitigil, mga ilang minuto bago huminto. My BIL said since direct sya battery, hindi sya dumaan sa relay at kahit alisin yung fuse hindi tumitigil so hindi din dumaan sa fuse.

He said baka yung busina na kailangan palitan. Hindi ako marunong sa electronics ng sasakyan. Tama ba sabi nya busina na kailangan palitan? Hindi ba yung pindutan mismo sa steering wheel? Ang alam ko kasi sa electricity pag cut mo ng circuit dapat hinto na, since yung pindutan ang nagka cut sa circuit baka iyon ang sira. Mali na intindi ko?

a number of cars have their businas wired direct to the battery, so's they can horn even with the ignition switch off.
safety/convenience and all that.
but i think they have their own fuse, naman.

yes, it's either the horn switch inside the steering wheel, or the horn relay.
it's probably not the horn. a defective busina either sounds hoarse, or does not horn when switched on.

the relay is probably easier to replace, as it's usually within easy reach in the engine bay.

googling the horn switch,
as with every other car part replacement procedure,
parang mabusisi, if one is not into doing it on a regular basis.

i'd probably have the mekaniko do it for me. i imagine only a few hundring bucks for his effort.

both procedures are google-able, naman.

good luck.

p.s.,
i still go banawe, even as it's inconvenient for me. it entails an hour's driving in traffic, to get there one way.
i find the mekanikos there, more knowledgeable.
and most parts for toyota, new or surplus, are very available there.

googling,
the switch/clock spring costs about a thousand bucks, and the relay less than 500 bucks.
