Greetings from Colorado, USA. I've been changing out some of the OEM parts on my 2020 Speed Triple RS 1050. Currently having an issue with a Yoshimura turn signal not working. The full left side signals work great. However, on the right side of the bike only the front signal works, while the rear doesn't light up. I've checked all connections, made sure the resistor is in correctly and even swapped the signal wires to see if the right rear signal actually work (which it does). Getting frustrated. Hoping to hear from someone with knowledge about the wiring and if they've had similar issues with the turn signals before I go spend a wad of cash at a mechanic's shop. Thanks in advance! Mark
McGuckin1050 Welcome to the family. Try an independent earth wire from the offending indicator to the frame see it works. Joe.
There maybe a short inside the indicator housing. Could be as simple as corrosion , caused by the ingress of water !
