    my turn signals work properly on the left side, but the right side is completely dead, the indicator light on the cluster doesnt even light up and all that happens when i turn the switch to the right is the flasher flashes super fast, thats it. The wire in the switch for the right turn signal was broke off and i fixed that, any suggestions as to how to fix my problem

    Does the indicator light in the cluster flash when the switch is set to the left? If so, then your right side bulbs and the wiring to them (at least to one of them) is OK. That would then say that you still have a problem in the switch, or from the switch back to the harness (Dark Green wire).

    yes if the switch is placed to the left the indicator does light up, the only other thing that i noticed is that the indicator for the highbeam doesnt illuminate but it does switch between high and low

    This is a different problem. Are both bulbs on the non-flashing side lighting, or just one?

    If both, then you've probably got one or both bulbs replaced with the wrong wattage bulbs (too low wattage).

    If only one is lighting, then the problem is the other one - burned out, bad contacts, or a disconnected or broken wire running to it.

    If BOTH of the bulbs (i.e. front AND rear) on the right side are lighting and staying solid, then you've got the wrong wattage bulbs. ---Edit - or, possibly, but less likely, there's something in the right side circuilt that's adding enough resistance that the flasher is not operating correctly, yet the lamps still light. Bad contacts in the turn signals could do that, I suppose, but I would also expect the affected lamp to be dimmer and maybe flicker when the turn signal housing is tapped.

    If only ONE of the bulbs on the right side (i.e. front OR rear) are lighting, and the other one stays dark, then the other bulb is burned out, has bad contacts, or has bad wiring.

    ok so i have a spare switch that i put on the bike and it does the same thing as the other switch, it works fine on the left side, but when put on the right all it does is the flasher clickers super fast, but the indicator light doesnt illuminate and none of the right turn signals work any suggestions

    I still stick with what I said before: either the switch or the dark green wire from the switch back to the harness. Since you verified it's not the switch, it pretty much has to be the wire.

    The dark green wire runs from the switch to one side of the turn signal indicator in the instrument cluster, and also to the front and rear turn signal lamps.

    The turn signal indicator in the instrument cluster is wired between the "live" wires for the left and right signals. When the left side is flashing, the ground for the indicator goes through the dark green wire and then through filaments of the right side lamps. Since the indicator is flashing when set to left, you know that the dark green wiring that connects the right side lamps and the indicator together is good. You also know that the lamps are good.

    Since you've verified the switch is not the problem, the only remaining place there could be a problem is between the switch and the wiring connecing the right side lamps and instrument indicator lamp. I can't tell you where along that wiring the problem is. You need to trace that out for yourself.

    Mac tools has a handy cicuit tester for diagnosing faults. SKU #ET120A for about $45.00usd. It is like a simple test light but is connected to both Pos & Neg battery terminals. When a terminal is probed, an led indication of red shows positive potential and green shows ground (neg). As an example if you probe a wire prior to a bulb and the cicuit hasn't been turned on, a green led is displayed. If it isn't green, then the circuit to ground is broken. When you turn on the switch the led turns to red indicating positive voltage. It can be a real time saver. By connecting only the black clip to neg, it will work like a conventional test light.

    Here is the site to see it

    I also am having a similar issue. My right works but my left doesn't flash or light up can't even hear the flasher. I changed the bulbs and still nothing. But when I try to start my bike and it doesn't start right away all 4 and the headlight light up. I am confused.
