Hi All, For some daft reason I picked up a wee MBK Booster on eBay and of course am now in the process of modifying it for no rational reason One of the things I've tried to do is change the stock headlight bulb for an led bulb which fitted great but went all wappy when I started the engine. Upon further investigation I discovered that the little Minarelli Vertical lump uses and AC system for powering the headlights. Can anyone suggest a simple way forward to get this sorted so I can see at night? I've heard of a floating ground, direct battery set-up and other random options.... Cheers - Ben
