Hi all. I would love some advice on an issue that has arisen from changing the rear fender on my R1 to a Yamaha tail tidy of sorts. it worked fine, but now indicators only work when engine is off, when its on the light flashes once and its gone. My local shop said it would be my wiring and looks to be an earth problem. I put the wiring back to stock and still persists. could the previous tail have an earth in it?? really stumped, any solutions would be appreciated.
