    2003 gp 1300 r not charging battery

    can someone tell me how to test my charging system, my battery keeps losing its charge everytime i use it. i put a fluke meter on the battery when it was running on a hose, the voltage read 12.3 even when i revved it up, it also reads 12.3 with engine turned off, after about an hour of riding the voltage is around 11.5, i charge the battery after every use.
