Add a battery, for testing it does not need to be on the bike just on the floor with leads long enough to connect to the electrics. Then repeat test with plugs on head.

Ok,thanks for the info,the consensus seems to be to fit a smallish AGM battery.Looking at it I could probably go that route with a little shift around of bits. I have got boyer electronic ignition along with a power box.If I were to get this battery would I take the feed from the battery to the powerbox or to the electronic ignition box.I think you can ascertain electrics aren't my thing,and I certainly don't want to mess up the Boyer parts.

Never had a powerbox, the 2MC ages then fails and as the powerbox has an equivalent buried inside then there are only downsides to its installation. The instructions I linked too have wiring diagrams which you can follow.
