Charging,?.

["Slack Alice" Simon]

I'm afraid I frequently talk ... erm ... nonsense.  

My excuse is I only apply half a brain to the question,   the other half is on the garden,   whether I can get a bike ride in,   and whether the engine I have just put together is too tight to run, and why.   Amongst other things.

If you are getting that sort of voltage at the battery, then the cut out is closing and feeding the dynamo output to battery.

So why is it not showing on ammeter?

I will add that to the list.   If you have that sort of switch panel they can need a service - dismantling , cleaning contacts and checking the spring pressure on the moving contacts.

And the brass tracks can crack, which can be difficult to see.

The half brain bit is - whether any of that will cause the ammeter to show or not - I can't work out just yet.

Cheers

Simon
