British Bikes / '61 BSA neg or positive earth?
« on: April 01, 2009, 10:20:14 PM »
Please can anyone help? I have a 1961 BSA Golden Flash which has a 6v battery for headlight and horn, at present it is negative earth but the battery is draining very quickly (over night) and isn't charging and the amp meter goes way up as soon as the battery is connected. Yes, it is my 2nd new battery. If I disconnect the Earth wire the battery doesn't drain? I know nothing about bike electrics but a chap who knows tractor electrics suggested maybe the bike should be positive Earth? Any advise gratefully received. Thanks.
