cbr 125 charging problem
 

Hi
After a long struggle #i managed to start my bike with a help of battery charger.
But when bike is running the voltage on the battery terminals is only around 6 volts. dosent matter if the battery is conneccted or not and dosent matter if the revs a higher than idle.
What can be the problem?

Could be a bad battery or bad alternator.
Try turning on all your lights. Do they remain bright? Does the voltage drop if you turn on the lights?
What is the voltage on the alternator terminals with the battery disconnected?
