Could someone tell me why my right turn signal just stops working??

Check the wiring from the signal stalk

Try a bulb type automotive circuit checker like the one attached. Attach the clip to a good metal chassis part and touch the ice pick end to each side of the fuses with the key on. If you find any fuses that the lamp in the device handle only lights on one side, replace that fuse.

Most of the time the problem is in the turn signal switch. The third brake light circuit bypasses the turn signals.
Someone would need to check brake light power in and out of the turn signal switch.

Most likely this is a brake light switch issue. Replace switch.

If your emergency flashers don't work, all flasher bulbs are fine, but flashing too fast, then check and replace Hazard light switch.

One fuse runs all your lights. Have you checked the bulbs? If they are set up for turn signals and running lights, they will have two filaments, one for the running lights and one for the turn signals. I'm pretty sure your running lights and turn signals are controlled by the turn signal cancelling unit. There is the chance that someone disconnected them. The older bikes didn't have running lights on them and that's how you could tell a Harley from the rice burners, not running lights. Just the headlight.

Good Luck

Did you check the brake switch adjustment.
Next to and behind brake pedal arm

OK, you've been thru the wringer. Unf, i cannot find info on where your flasher is, but there are a couple common places to check. It's usually under the dash on the driver's side. Sometimes it's plugged right into the fuse box. Other times it's clamped to the steering column or under dash. Sometimes it IS behind the glovebox--not IN the glovebox. See if you can get behind it, either pull it past it's stops or get under the dash and look behind. You may have to pull a panel off or something to see in.
I'm pretty sure they wore out your flasher and it was really bad advice to tell you to replace the signal switch in the steering column. :o(

you prob got a trailer plug prob bad wires if not tail lights run through turn signal switch tell fix ya bout me ok

Probably a bad grounding, causing the current to go other ways than intended i.e through other lamps. Check for corroded lamp sockets or bad ground connections in the tail light assembly, also check the lamps so they are ok.

Good luck!

sounds like you've blown a fuse when the relay packed-up!!! The Fusebox is under the seat, it's next to the battery on the left-hand side (as if your sat on the bike), the 10amp fuse in position 4 protects the horn, indicators, stop light, instrument memory and diagnostics. You'll have to buy a new fuse 'cos the spares in the fusebox are 20 and 40amps!
