Hi everyone from a noob to the Org. I'm going to launch straight in with a question in the hope that someone can help!

I have an 01 sv650s which has been fine up until now. I ride it every weekday, doing a 100 mile round trip for my commute. Everything was fine until wednesday morning when it wouldn't start due to a flat battery (typical sounds of failure to turn starter motor sufficiently). I charged the battery back up today and carried out some tests, following the Haynes manual.

Unfortunately I dont have a multimeter but I do have a battery/alternator function tester with led lights that come on at various voltages. I connected the charged battery and it lit up the green 12.6v light with the ignition off. I started the bike and turned on the high beams and the heated grips and the 12.6v light started to flicker, reverting mostly to the yellow 12v light. I revved the engine to 5k and the yellow 13.2v light came on but no more (the next green light, 14.5 did not illuminate). Switching the lights and grips off and letting it idle resulted in yellow 13.2v.

Does this sound like anything is wrong? I think there must be a fault somewhere as I definitely do enough mileage to keep the battery charged up. Would there be a battery problem or reg/rec?

Thanks in advance and apologies for lack of knowledge!
