I wish to repair a faulty dynamo light system however I am a complete newcomer to these systems.
I bought an old bicycle with a bottle dynamo ("Vitalux C 6V") connected to the rear wheel. There is a single wire connected from the dynamo to the front light. There is also a single wire leading to where the rear light should be, but the light has been removed, with the wiring just loose in the air where it should connect normally.
When I connect the dynamo to the tyre and spin the wheel the globe does not light up.
Is it possible to have this system functioning without connecting the rear wiring to anything? To what and how should I connect this wire if I need to complete the circuit?
The wiring at the from the dynamo to the front globe had been cut so to reattach it I stripped some of the coating and twisted about 1cm of the internal copper wiring together. Could this be the problem and would using a length of unbroken wire potentially resolve this problem?
Thanks for your help.
