well, here's something that I learned today. yes I'm in the talks with the dealer to get it replaced. I'm gonna re-check today again if I can jump start with the battery in then and report.First - I would contact the dealer for a battery replacement on a 2021 motorcycle. Second, and to answer your question. You cannot disconnect the battery while running because the battery needs to be inline to complete the circuit. Regardless of the size or brand of the bike that is a modern solid-state ignition requirement.
This is interesting as in cars this is definitely not the case. It's even sometimes advised that the battery is disconnected to in order to be able to jump start properly. I will test this today again though with the battery connected. Thanks.First - I would contact the dealer for a battery replacement on a 2021 motorcycle. Second, and to answer your question.

Good to know! thanks.And definitely not a car or bike with an alternator, so everything since 1970.
You can easily end up with a fried regulator by leaving battery out of circuit as alternator has no reference voltage from battery so keeps upping the voltage till something gives off smoke.
hi Ray, the battery is showing 0 volts when checking with a multimeter. I don't suspect of a fuse because the jumpstart works. That's a good idea, connecting 2 batteries and try to charge them that way. Gonna try that later. Thanks.If the battery is really flat a modern battery charger won't sense there is a battery there so won't commence charge cycle.
Sounding like battery is bad condition.
Do you know what voltage it is currently?
Have you checked the fuses on the bike?
You can try getting the charger to start by putting another battery in parallel.
The idea is the charger senses the voltage from the good battery and commences charging. After a little while remove good battery.
After charging go have battery tested to see if it can supply enough current or it needs to be recycled.
If the battery is bad then it is time for a quality agm. Heavier yeah , but the weight saving is not that huge.
But how jumping or push-start the bike will work if the bike does not stay running with the dead battery?The first thing you should do is check the battery voltage static with no draw. Then watch it as you try and start the bike and see what it drops to. Sounds like a bad battery and yes, they can just go bad. No, there is no "hack" to save you if this happens other than jump or push-start the bike.
