Bike Model = : GT650R 2007
Hey guys desperately need help. Got a 2007 GT 650 R I’m getting no dash lights or lights.
I have checked the battery. I’ve checked the fuses, checked all connections, ignition switch, confirmed that the dash is receiving power And so is everything else. I’m stumped and I extremely frustrated. Any help would be greatly appreciated! Thanks and happy Sunday! -
Hey,
If there is power to the dash itself, this assume the harness’s orange and red wires are feeding power to it.Did at any point the bike had a faulty reg (cooks up dashboards) due to overcharging etc or was there any signs of damage to it that caused water to invade its cracks then fry the circuits
Also, does the “RPM” (Just the RPM side) light up at all? (There is bulbs under the RPM side, they don’t care of the LCD glass is on or not.) the use primarily an orange live wire. In some cases it stays OFF , until you go to the killswitch => turn on the “lights” (headlights) , the RPM counter will also turn on as it assumes you’re in night-riding mode. On later bikes, it’s always ON.
Other Lights = Do you mean headlights ? => Check your relay isn’t burst and the 4-pin relay is getting power to the socket. Also both LEFT & RIGHT switch-gears on your handlebars also control your headlights.
Rear Lights = ? You have not mentioned if they turn on? If the brake light is even on when pressing brakes ? Will wait for your feedback here.

Hey Marcel thank you so much for your response. I left some information out. You are correct none of my lights are working. Tail light does not work headlight brake light even when engaged doesn’t come on. also know the RPM side is not lighting up either. I’ve checked everything the orange wire from the ignition to the dash everything is getting power. You did bring some things to my attention that I haven’t checked yet.controls and the relay.

check there is 12v at the brake switches too, if yes ==> check the wires at the bulb socket at the tail light.
Brake light will always turn on, otherwise the bulb is dead. The brake light does not need a relay or front handlebar switch gears, only brake switches turn them on. (Later EFi models have relays for brakes) but you have an older model with less electrics , so it should be easier to diagnose.
Also remove the bulbs in the RPM side , and check they are not blown ?

Also for headlights, if relay gets power = It will always make a “click” sound, if it clicks , then your headlights should turn on.
Usually the handlebar switches control that relay too.Circuit is
“Headlight => Left Switch Gear (Hi vs Low Beam) or “Flash Yellow Button” ==> Right Switch (Turn headlight on or OFF , also RPM counter unless RPM counter is always in “on” mode) ===> Relay clicks and sends power to the headlights. => If previous owner put 100w bulbs => It will fry the harness and everything else and possibly regulator and stator but i hope it is 55w on both bulbsAlso very old bulbs are annoying to the battery and bike won’t start (if bulb is too old, resistances is too high or wire gets very hot) – I found out the hard way last week when a wire burnt my hand for the low beam, the bulb was a cheap knock off that was in the bulb, it worked so i didn’t think much until i fought through 4 batteries to find out the bulb has been eating up too much energy. I learned my lesson to stick with premium brands like OSRAM or Philips if i ever buy another 2nd hand bike haha.
