Please, do not email me asking for wiring diagrams. I don’t know much about any scooters other than the Honda Ruckus. I also did not make this wiring diagram.

Ruckus runs fine – No Electric Starter – When I remove relay instument and tailight cease to function but electric starter then functions – Yes I am depressing both brakes. Where do I look?

We have a 09 ruckus, the ignition switch is removed and replaced with a toggle. Currently every part of the frame has charge, electric start dose not work, and when the toggle is in the on position no accessory lights function but the horn dose…. Where are we wrong?

I know I’m late to the party but you’ve got an open ground cable. Either the ground isn’t connected or the wire is so corroded that it cannot make the path to the battery.

I am having the same issue with my 2013. Were you able to diagnose this issue? I tried a new ECM and battery without luck. Really need to get this ruckus going again. Any help would be appreciated greatly. Everything has power for just a second then starter relay just clicks.

I just bought mirrors with turn signals built in the mirrors. There is also a red light in each mirror, and they both have 3 wires coming out of the bottom. Yellow, Green, and blue. What do I have to buy to get the turn signals and red lights to work properly on my 2016 Honda Ruckus. The turn signal relay is round, has 2 pins(rectangle shaped), and has only a gray and black wire coming from the relay plug.

You only need to find the positive and negative wire on the mirrors, the 3rd wire sounds like its a constant current to keep the light on all the time for some reason. But if you want it on all the time figure out what wire it is and hard wire it into the gage wires, they are black with white stripe and green with black stripe. I ran a red light strip (underglow) to my Guage wires so when I turn my ruckus on the red light comes on and looks really good at night glowing red under foot platform.

Does anyone know why my service port (red power connector) kills my motor when I try to reset the ecm. I’ve watched videos of people doing so by taking a piece of wire and putting it into the plug ( one wire that goes to the red plug) and then touching the wire to the positive battery terminal while its running amd dont give it amy trottle it’s supposed to kill the head lights and then take it off of the battery and the headlights are supposed to come back on and then it’s reset. I’m trying to do so because my ruckus is only and has been since I bought it 34 mph. I changed variator rollers and got it to get up to almost 40mph but the rev limiter stops it from going faster but in the past few weeks of changing the rollers it’s dropped back down to 34 mph. Can anyone please explain what could cause any of this? I have new ngk plug gap is correct, fresh oil change, clean oil screen, fuel filter is clean, carburetor has been cleaned air filter is new. All things maintenance is good on it but will not go over 34mph even down hill. 15 to 20mph up hills. I live in Madison Indiana very hilly are it’s right by the Ohio River. Thank you if you took the time to read this.
