Zombie thread alert!
06 S2R 800, just under 40k on the chassis, notionally 15k on the engine (and it feels healthy enough) from an SS800.
I've been having this issue, but I changed a bunch of stuff at once. The bike ran fine but for a couple of strange electrickery "tics," among them this turn signal flashing business.
So, today on the commute home I was overcome by the hoon on my shared, private, no-speed-limit-having access road... and the bike just quit. At first it refused to accelerate, and then shut off completely.
Nothing. No lights, no starter, and the dash is immortalizing the speed I had achieved in conjunction with RPM.
I called my local rescue provider, and he came to tow me the mile or so home. As I was waiting, I teased out the main fuse from under the tank (ST tank has a protective cover and I didn't have the allen wrench to remove it) and it is fine. I tease out the fuse box (some might consider the under-tank organization of wires and such to be defined by the word "janky") and all the fuses look good.
I took off the seat to look at the battery (li-ion, and that's where it fit) and at first glance it looks fine. Back in the garage I look at it again, and the "marine grade" battery lead I used (one of
these) has melted all the insulation off the black wire and it has a break.
Theory: The turn signal flashing is telling us the voltage from the battery is not right after turning off the bike. In my case because the wire was the wrong size for the application. In other cases, maybe battery, and maybe other connections.
