i have a 00 r6. my question is, when i press the brake my headlights and my speedo dim. when i apply a volt meter lets say my voltage is 13.50v, i press the brake and the voltage drops to approx. 12v. is that drop in voltage normal? im a newbie at this but i came to the conclusion that the drop in voltage when the brake is applied is dimming my headlights and speedo. can anyone give me some help. thanks
