Not sure about the battery, I haven't had that problem.

I assume you tried unplugging and plugging back in of all the connectors, front and rear? Other than that I really don't know.

I used to have problems with the wires behind the headlight getting pinched and not working at all, but I couldn't see how that would make them flash quickly...hopefully somebody will hop on that can help you more than me.

Good luck and if you find out let us know.
