Suzuki GT250 turn signals and horn

I'm down to my last two items that I need to fix before I can get my bike roadworthy but I can't for the life of me figure it out.

My rear turn signals both work fine but the front two are giving me nada.

The only thing I can think of is that I replaced the headlight ears with some universal ones like these

and in order to attach the turn signals I put rubber grommets in the middle holes. Do the turn signals need to be attached to the metal directly in order to earth?

I also can't seem to get the horn to work. It is wired correctly but no toot. For some reason the other day when I put the headlamp back in it honked (scared the sh1t outta me) but nothing since. Any ideas???
 
Thanks! indicator problem solved.

Now the horn :mad:

There is definitely power, checked the wire with a test light, just no honk
 
Is there any way to test if it's the button itself that's the issue?

If any other GT250 owners can tell me how theirs are wired i will be forever grateful, it's the last niggling issue before I can get it registered and enjoy it :)
 
I peeked at a GT250 wiring diagram online. It looks like the horn is wired hot, and the switch grounds the circuit. With the key on, you should have a hot wire on one side of the horn (it's orange on the diagram I looked at), correct? If so, take the other wire off the horn (green on the diagram), and using a jumper wire connected to that terminal on the horn ground it. The horn should honk. If it does not, you have a bad horn. If it does, you have a problem in the button or the wires in the button circuit.
Those wires aren't hard to trace, but are a little more involved. Make sure the horn works first and go from there ;)
 
alrighty, hooked up the horn to the orange and to ground. Bit of tweaking of the rear screw and lo and behold, it honks so it isn't the horn. There is something amiss in the switch wiring I guess.
 
I had the same problem with my CL360. Pulled the entire switch apart and ground clean metal so to ensure a good grounding. Sprayed dielectric grease into ALL connectors and them found out the wires that actually went onto the horn weren't connected. All that to say, don't forget the small stuff.

Go through each step out the wiring system and clean/check with a multimeter. Spray Dielectric grease (like $5 at Walmart if you don't have it) in all connections and check them with multimeter. There's rarely a simple answer to electrical questions. Its just about being diligent and going through the whole thing to isolate the problem. Pain in the ass I know. Post up if you need more help/stuck somewhere.
 
I checked the button with the test light (don't have a multimeter unfortunately). The there is power coming from the green wire to the button and when I push the button the light comes on. Must be a ground issue somewhere.

Green is the power wire right?

I think what you want to check is whether the white wire has power when you push the button in. I'd have to see a wiring diagram to be sure, but it'll be pretty tough without a multimeter. If your wires are broken/frayed somewhere they could be grounding out (Aka, shorting out the circuit). Unlikely though. Wires don't usually fray easily.
 
Eureka!!!

The entire left hand switch itself needed to be grounded. I have clubmans on there that mustn't allow it to ground properly. Once I touched the switchgear to the to the frame and pressed the button it worked :)

God I hate electricals
 
Glad you got it working. Just about checking all the little things.
