Apologies if this sounds a little basic, but I have recently become the owner of a 1974 suzuki A100 bike (and have no maintenaince experience). Runs generally fine, but small glitch in the electrics I think. The 'B' (battery?) light is constantly on, and never goes out. Electrics operate OK, except indicators <fade> not <blink>, at low revs, showing me, I guess, no charge. Am I right in thinking a) battery is dead? b) wiring problem? c) charging coil (as suggested by someone - if so, don't know where to start with that one?). I realise all three (or more) could be possible, where do I start? I believe it runs off a 6v system. Any thoughts/ideas welcome. Appreciate your time. Chris.
