I don't know whether my symptoms are considered similar. There was this period of time, sometimes when I stop at traffice light in Neutral, with signal light and brakes, the engine and temperature indicators might light up. The rpm bounces between 1 and 0. Once, the engine even died on me. When I checked with the service centre, one of the staff suggested unplugging the main fuse and giving the contacts a good clean. It worked but have to be repeated every so often.
Since having my fuel pump replaced, the above symptoms (engine + temp indicators light up, engine dying after braking+N+signal) never appeared again. But nowadays, when I start up the bike (not yet the engine), the light is usually quite dim. I'm wondering if my relaxed riding style is causing the battery to be insufficiently charged, or is the alternator undersized, or is the bike's electrical load too much?
Anyone encounter similar electrical problems with their bike? Any experts can share? Is changing the alternator possible, and will it help?
