Firstly, what bike engine is it? (if its a fireblade could be relatively simple fix)

probably regulator / rectifier

sorry dont know will find out.
cheers.

Likely the regulator- quite a common failure on BECs.
On some charging circuits if the battery goes TU the voltage goes stupidly high so there's an outside chance its the battery not the regulator (but its less likely).

Firstly check what he means by overcharging, the battery on a BEC will show between 14-15 volts when the engine is running.

If it's more than this then it is most likely to be the regulatorrectifier and it will be pretty simple to change so no big issue.

HTH,
Rich.
