Sounds like you need to check the generator and charging circuit.
The bike will start and run on the battery alone until it is drained.
Once a bike has been started the battery power is taken over by the generators power this also replenishes the power lost in the battery when the bike is initially started. If the generator does not generate power the bike will continue to us the power from the battery until it is exhausted and will therefore stop.
A simple test is to turn the bike ignition on and turn the headlamp on (check the brightness of the lamp) Start the bike and re check the brightness of the head lamp, it should be a little brighter if the generator is working. Another test is carried out with the use of a voltage tester (multi meter). Set on dc volts test the batteries voltage eg 12vdc, start the bike and re test the voltage should be around 13 - 14v dc if the charging circuit is working
How old is the battery? You need to check if the alternator is putting out a charge, is the regulator working. A dead cell in the battery will often show a full charge state if you try to charge it. When you try to start the bike the battery is required to give a high charge to the starter. The buzzing you hear is probably the starter solenoid trying to work. I would suggest fit a new battery and if the bike starts OK check out the charging system. 14.4 volts is the normal reading across the battery with the engine running at 5K.
What age is the bike? older bike will not charge at idle. you will know if the bike is charging by measuring theu voltage of the battery with the bike and all accessories switched off if it is a new battery it will be above 13V A dead battery will be about 11V anything under this and it probably will not recover by charging and you will have to buy a new battery.
ok so lets say the battery is holding 12.5 volts if you start the bike and rev it up and it show higher than 12.5 volt your bike is charging note some bike dont charge under 3000rpm.
the battery may seem ok, but it's obviously discharging itself or not charging during riding.
Try this...charge the battery with a battery charger. disconnect the charger, and put a volt meter on the battery. Start the bike. Rev up to 2000 RPM. If the voltage is not HIGHER than it was before starting the bike, there's something wrong with the charging circuit. If it IS charging, turn the bike off, and disconnect the battery overnight. If the bike will not start the next day after reconnecting the battery, the battery needs to be replaced.
If the battery is NOT charging at 2000 RPM, the charging circuit is bad, and is likely what is draining the battery overnight.
Have your charging system looked at, first do a simple multimeter test, get a multimeter, switch it on to Volts, start bike and see what it reads, put multimeter prongs directly on battery, very simple, if its below 12V you have a charging problem. If your battery is new and your charging system is faulty the bike will start and go, but when you switch it off the battery will be dead because it has not been charging. When you let a dead battery sit for a while it will charge itself a little, enough to start the bike up. Have you ever had a flat torch or mobile phone, it will die when battery is flat but when you try and switch them on again after a little while, they will work a little and die again, same with bikes, cars etc. All the best, Forever Two Wheels :)
ya i have the same problem and the clicking from my battery either the battery is done for therefore wont charge or it didnt charge long enough try an overnight charge if it dosent work then afraid its 50 quid for a new one
Fully charge the battery, measure its voltage, put it in the bike, start the bike, run the engine at 1,800 to 2,000 RPM. Measure the voltage on the battery (let's say it is 12.2V). If the voltage is not higher than the battery's voltage was before you put it in (12.2V in the sample number I pulled out of thin air, above), the charging system does not work at all. If the voltage is higher than what you measured, but is not 13.8 volts or higher, the charging system seems to work some, but not enough. Perhaps the voltage regulator is malfunctioning, or the alternator has a bad diode.
Sounds like you are not getting a charge from the alternator. You need to check battery voltage with a meter with the engine off, key off. Then again with it running, and the voltage should increase. If not, it's not charging.
