    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.

    Replace the battery. A load test should show that while it can supply 6v
    initially it is unable to supply any current. Twenty years????
