@@SuperRetroville I look forward to seeing them. Meanwhile my 6 Volt C45 dynamo is not exactly like yours and I'm struggling to see how to adjust the third brush. Do you know if there is a standard way or do they vary a lot?
@@RobertBoulstridge I'm afraid i've never taken one of those apart, mine is a 12V C45A. I have seen different methods of holding and pushing the carbon brushes and some 3rd brushes don't have a screw to move them, you just have to push the assembly round through the window. This is an extract from the Lucas book "Remove the dynamo cover band. The control brush can be moved by firmly pushing the holder by means of a suitable piece of wood. The adjustment is very sensitive, only move the brush by the width of a commutator segment before checking the output. To increase the output move the brush in a clockwise direction as viewed from the driving end (for clockwise direction machines).To reduce the output move the brush in an anti clockwise direction. The ammeter reading must not be more than 4 amperes when the head, side and tail lamps are switched on, using bulbs of the same size as those specified. This must be checked immediately on starting the engine and not after it has been running for some time."
@@SuperRetroville Thanks very much for your reply. I have worked out now how to move the third brush but I didn't realise the sensitivity nor the max. current criterion. I'll get to work!
Brilliant video(s) - thank you so much. I've seen two videos and assume that there is a third but can't find it. Is there a third?
Thanks for your kind comment. Yes two more to come... Refurbishing then reassembly and test.
