Have lost my BMW Manual, where is the Earth lead ? Battery keeps going flat on it. It now has a brand new battery which I\´d left on trickle charge. So it started fine, so rode it over to get an MOT. A week later Battery totally flat. A friend has told me perhaps it has a dodgy earth lead? Any other suggestions other than a new loom? Oh the bike has no indicators. But still has a mountain of wiring curled up in the headlamp casing. Its an ex police - I\´ve had it for 18 years! Thanks
