Only used this for a couple of hours so far, but when I came home today (took the car today. didn't ride) the PCS was flashing away constantly on the handlebars.
It was the same sequence you get when you connect the batt to the lamp (self-test, followed by x blue flashes for #volts and y green flashes for #1/10 volts - charge was about 7.5v. Only as soon as it should've finished it would start over again, and again, and again...
Can't find any mention of this repetitive behaviour in the manual, is it trying to tell me it would like a charge?
