Hello everyone, I confess this is not specifically related to BSAs. I guess it could apply to any bike, but the reason I'm posting this is because of a problem I have with the battery on my (2011) Bonneville T100. I hope that's okay, this once., given that it could apply to a BSA.
About, say, three weeks ago, when I went to start the bike, the battery was flat (just a click sound when I pushed the starter button.) I stuck my Optimate 3 on it and charged it up, after which the bike started.
I last took the bike out about a week ago. This morning I went to start it (having put on my thermals etc etc!), and...you've guessed it, the battery was flat (just the click again.) My question is: does that mean the battery needs replacing?
I have put the Optimate3 on it and the Optimate's LED3 light has come on. I find the booklet hard to understand, but I think that means the battery is extremely flat, and (not sure) it might be that the Optimate's recovery mode won't engage unless the battery is disconnected from the bike (at present the Optimate is just connected via the wire which sticks out from under the seat specially for it.)
Anyway, has the battery had it? Phil.
