Last weekend at Tally I lowsided at the carousel. The bike went end-over-end and the instrument panel ended up a long ways from the rest of the bike. Anyway, plugged it back in and the bike started but both turn signal indicators flash together, quickly. The bike seems to run fine, don't know if this is just an electrical glitch from the crash or the computer trying to tell me something is wrong. Any ideas??
It's possible your hazard light switch is on or shorted. It's the red (I think it's red) button on the left handlebar control switch.
I don't know why they are flashing, but the quick flashing indicates a bad ground or lack of a ground path.
