Help Please! I've just got my 1960, 6 volt, coil ignition, 600cc, Dommy back on the road after a long lay-off and I'm plagued by a bit of 'no start, flat battery' problem. Everything seems OK initially and even though the battery is about 20 years old it seems to hold its charge when the bike is not in use. Start up from cold is good but after about 20 minutes running the 'idle' becomes a bit erratic and the engine will quite often die on me. Investigation quite often shows that the battery has gone totally flat on me and no amount of kicking will get it started again. Leave for about 30 minutes (time for a beer/coffee!) and the battery has recovered enough to give a spark and we're cooking again. The ammeter shows a bit of a charge while the engine is running although it does 'kick' about a bit at about 60 mph and the 'emergency' position about doubles the charge rate. I'm thinking battery or rectifier, is it possible to test latter? An help/comments would be very gratefully received.
