Hello, long time no see 
I am having trouble with battery lately. After I charge it with charger and drive motorcycle for a while it has some trouble starting (I can see it almost does not start up, and if I try to start it few times in a row it can't do it after second or third time.
So my guesses were - faulty battery, faulty electric installation (shorted) or something with charging. So it did test:
- battery after charging with external charger and leaving for a while - 12.6V
- while starting motorcycle from fully charged battery - voltage drops for a while to about 9V (and when I do it second and third time it drops to about 7V)
- when idling and everything turned off - 14.4V
- with lights on and idling - 13 V
- with high beam and idling - 12 V and dropping
So what are your guesses - are voltages are OK on idle? I thought it always would be 14.4 even with lights (because voltage regulator should turn it up?)
Thanks!
