Hi everyone,
I would need some advise here.
As i like to travel or move around in the night most of my time, but my head-light will brighten up a lot with ramping the rpm above 2 or 3 during stopping.
Once release the throttle, the light dim down again.
I have check, there is charging (i have a volt meter wire to it, during running it show 13.6v to sometime 14.2v. When at stop show 12.3v with rpm around 1.3 to 1.4 and everything off with card key out 12.7 v)
How can i solve these problem?
Will adding another 12 volt battery wire parllel to it help?

Thank you
