what's going on guys dave here working on a suzuki gsxr 750 but this is going to apply to
any motorcycle or any vehicle for that matter uh the issue is the horn was not working very strange
because it was working and then it decided to quit alright so we need to troubleshoot exactly what
is the problem all right you'll just need a couple of things i need to get you a multimeter like this
i'll put a link down below but you can get this at any hardware store or electronic store or auto
supply store you know this is a basic multimeter that has two leads coming off of it as you see
and you will also need just some basic wire with alligator clips you know two of those
so that we can test the battery straight from uh you know from your 12 volt battery
so let's take a closer look at all this okay so we need to determine what's at fault here
you know is there a fuse blown so you need to check any fuses relating to the problem
uh we need to see if the horn actually works if we feed direct power to it so you could just put your
your little wires connected to the battery we also need to determine if the connector for the horn
would be this guy here for this particular model make sure the connector is good and getting power
when you actually press the horn button on the handlebar wherever yours is located and this
could be for a car or anything all right so first we will we connected our leads from our multimeter
we set the multimeter to 12 volt because that's what we're dealing with it's a 12 volt system
okay and then you'll plug your leads you know into each wire for the horn
okay then we will turn the vehicle on
and see what the multimeter tells us
pushing the button
it tells us the connectors are getting power
when you hit the button all right so that eliminates a fuse issue
it should eliminate the other connector being an issue but that doesn't totally eliminate it it
eliminates uh you know wiring issues that sort of thing okay so moving on let's test the horn itself
okay
let's test the horn all right so it won't matter which which terminal you use it should make a
sound either way if the horn indeed works okay so we're just putting our negative on one prong right
here and we'll take our positive coming from our you know coming from our battery positive
touch it to the other one and if the horn works you should hear something here we go
okay the horn obviously works
all right now disconnect all your stuff so you don't possibly
ground anything all right let's take a look at other things now okay that means
there's a possibility of the terminals here being a little maybe they're a little crusty
these guys in here they might be a little crusty so you could take you some you know some
sandpaper or some emery cloth or even a hand file or something and clean these terminals
off here you could also use some contact cleaner or maybe some dielectric spray or
something just let's clean off these terminals and see if that makes any difference also
okay and you should also do the same thing with the connectors it's themselves
because it's possible maybe they've got a little corrosion on them
so with the connectors down in here you may want to take uh you know see what you making spray some
you know some dielectric cleaner or some contact cleaner you might need to try and clean them off
a little bit with a maybe a thin little brush um maybe a little metal bristle brush you know
something that's got some texture to it see if you can clean off the connectors inside there and then
we try it out again
plug her in here make sure that make sure that it's in there properly of course
turn the key on
and there she goes and again it doesn't matter you know you can flip it around and
install it the other way as well you know horns it really doesn't matter which one
it works either way so don't get too picky on how you connect it anyway and uh i mean yeah
like i said if if you're getting power showing power through your multimeter
that also eliminates the switch as the problem but if you're not getting any
power to the multimeter you need to investigate is your switch assembly
needing repair replacement uh is the wires themselves having a problem you know is
do you have a phrase somewhere you know that's that's also eliminating the fuse being a problem
and that's pretty much it you know horns are simple but motorcycles they sometimes flake out
with the horn and a lot of people don't don't care about having a horn but some people do
i actually like having a horn because stupid motorists ignore you sometimes out there and uh
you know there's nothing else you can you can't yell at them and they won't hear you anyway so
i use the horn quite a bit to keep motorists you know alert to my presence if i'm on a motorcycle
or you know sometimes they'll weave around and try to cut you off or whatever and you can just lay on
it maybe it doesn't do any good but i like having a horn working on a motorcycle anyway that's it
check out other videos we've got all kinds of cool stuff um we're doing some videos
relating to this suzuki gsxr 750 we do videos on dirt bikes yamaha yz450f yamaha yz 250 fx
yz250 two-stroke even an older yz250f all kinds of videos relating to motor vehicles
as well as stuff around the house and lawn equipment and whatever you know if you just
search through our channel you'll find all kinds of cool stuff on on fixing things and
doing basic repairs and you know stuff like that anyway horn resolved so
uh google horsepowerhouse we are on ebay amazon facebook and uh so check us out we
have a pretty cool store relating to motorcycle parts and tools on ebay and amazon that's it
hope this helped you guys out you'll have a good day we'll see you later
