i have an 81 cb650c and am having trouble with it. my bike is draining the battery when i ride, i have a local shop telling me it is either the stator/rotor or the rectifier, my buddy has the same bike just not the custom version and is willing to let me put his rectifier on mine to see it if its that but i need to know the voltage comin out of the rectifier back to the battery b4 i just take off riding and risk getting stranded again so if anybody has this info i would greatly appriciate it so i can try and get my bike ridable again thanks
