I'm looking for a parts list or exploded diagrams etc. for a 1931 Lucas dynamo. It's the one with the built-in regulator/cut-out. For some reason I can't find much info on these devices and I'm trying to rebuild one at the moment which is largely complete.
Hi Bruce.. The set up is notoriously unreliable on these '3 brush' units.
The chap who does my mags and dynamos has converted quite a few to the '2 brush' spec with a separate regulator..This can be done without altering the external appearance of the dynamo....Ian
