Hey all, i have done a number of searches on old posts but havent found a straight answer.
My bike failed to start this week, on trying the starter motor slowly wound to a halt hence the battery obviously was flat. So I ran a volt meter across the terminals and it read about 10.8v.
Bought a new battery, installed it and checked the voltage with the engine OFF, reads 11.9v. Started up beautifully So I once again checked the voltage across the terminals this time with the engine ON. At idle the voltage is around 13v. I rev the engine to 5000-6000rpm and it reads 13.9v.
Now the threads I have read say that 14v or above is normal charging voltage for around 5000rpm.
My question is, does what I have described above sound normal? 13.9v charging voltage across the battery at 5000rpm / 13v when idle / 11.9v with the engine off?
Thanks
