People 50 2 stroke. Starts and runs good, but I have a serious dimming of the headlight when touch the brake. Turn signals will cause headlight to pulse, until I apply brakes . Alternator unit, so headlight doesn't come on untill the engine is running. I think that's because it gets its power from the alternator, not the battery. The battery has plenty of power. So, any ideas why it's sucking power from my headlight?
Thanks
