My bike has developed an issue. Has a brand new battery, runs perfectly but when I switch it off after a run the battery has gone flat!
On tick over the bike is putting out 12.56 volts when I put a multimeter on the battery, to me that doesn’t seem enough.
many advice?

 

Sounds like it might be Reg/Rec or stator
You should have around 13v at idle and 15.5v at 5000 rpm with the headlights on.

 

ok thanks buddy, I’ll work through that tomorrow, currently got the battery on charge.
thanks again
