Hi all, so none of me lights are working i have replaced the headlight relay today, that didn’t work. Also is the headlight relay responsible for brake lights and dashboard aswell? Could it be a wiring issue? I will get some new bulbs n see if that does anything but I suspect its something else.

Headlight Unit:
- Controlled by both right switch (it turns it off or on) => All carb models or early 2008-2009 EFI GTR.
- Controlled by left switch too (high beam , pass/flash , low beam)
Press the “Yellow button” on the left switch , the headlight must flash
Does it?
Rear light = If your rear of the bike uses BULB type (big giant red cluster unit) , it will be on all the time usually , but older GTR will have it OFF until rider turns lights on from the right switch.
Brakes = Must always work, regardless if the headlight is dead. Brake Switches trigger the red light at the back directly. Controlled by a 15A fuse in passenger area.
Dashboard = Red wire (usually) on the harness turns the LCD glass on. but i can’t comment further until you upload a picture of your dash, Hyosung has made a few variations of them (later ones using SMD LED’s directly on the board, older ones have bulbs on the REV side only but LCD glass has its own light source under the glass to illuminate it. A picture would help.
Indicators = Left Switch Gear & 3-PIN Relay control it . There is a socket for 3-Pin relay, this is for indicators only. Left switch controls them directly , while the dash also gets a signal from them to tell you which side is flashing.
Worst case? = Remove harness, and check all related wires are “complete” end to end so there is no dead signals going from the bulb to the switches or relay. Time consuming but well worth it and a pocket meter helps a lot.

marcel cheers for the reply you legend. So i im here looking at the bike now n was thinking when i got the bike and cranked it over for the first time, i did smell this burning smell coming from the dash area so i shut it off. So i take my fairings off have a geez at my dash harness clean it up abit but must have over looked where the smell came from. So im here looking at the loom now and see the wiring for the hi beam looks like its all taped up n jank so im assume thats where the smell come from. maybe the wires touched? Would the jank, taped up wiring connections for the hi beam cause the thing to shit itself?
i do have a spare harness with me im using to figure what wires go where. Might i add there are absolutely zero lights what so ever only one bulb in the bottom of the rev counter

Use the “Add Media” button on the reply box , its the green button as you’re replying to us.
Then select “Upload” , it will ask you where your picture is
Eg. Phone, tap your phones gallery folder inside the pop up window , so the site can fetch it. Give it a minute or two if its a big image.

Sorry but for the life of me I can absolutely not figure out how to post pictures. Must be my iphone
anyway its the old black dash, none of those top lights onnit just the select and reset buttons. black rev counter. 1 plug and about 3 other wires going into the back of it
any way the headlight is my main concern with the bike as i need to be able to ride at night
so going back to my previous question. If say the wires for the hi beam light possibly got fried could that have done it for the whole light?

The headlight will have 3 wires going to it under the headlight shell ==== Yellow, White , Black or Grey
You must get 12v out of them or you may find that the smoke/smell you witnessed before could be from down there. maybe previous owner put “100w bulbs” and caused the fry up ? It should be H1 and H3 at 55 watts each max.
Dash = Open the unit itself and look for burns.
The rev-counter should still light up on its own and has its own bulbs.
The LCD glass has its own power line (usually red or orange wire going to it)
