[QUOTE="timetraveller, post: 173053, member: 456"] Follow LoneStar's advice if you can but you might find it much easier to take the dynamo off the bike to play with. You can, for example, clean the commutator on the armature with everything in place by just removing the end cap of the dynamo. The commutator is the thing with lots of segments and these get covered in carbon dust from the brushes and oil from anywhere. A petrol soaked cloth will remove the dirt. Just hold the cloth against the commutator while someone carefully kicks the engine over. In addition the carbon brushes wear and can get stuck in their housings so you need to make sure that one or both has not worn down so much that it is not touching the commutator and that neither has stuck. They are spring loaded and the springs could be weak or even broken. Have a go at these ideas and then come back with the results. You might just get lucky but that cylindrical regulator should go. They were a pain in the rear seventy years ago. [/QUOTE]
