dynamator

[John Mason]

I also still also run on 6 volt with my Ruby. I have a modification to my charging circuit made by one of our club members (PWA7C). By wiring the Dynamo slightly differently to make it a 2 brush unit and fitting an electric gizmo made by him it allows the battery to charge at a higher rate without damaging either the dynamo or battery. I have had it fitted now for over 4 years without problems and always have a battery with a good charge. I was about to say full charge but that would be incorrect as it goes down when pulling on the starter. However not long running before its back to full charge.
