Good morning from Austria, the E3L Dynamo does not provide any voltage, only approx. 0.15 volts. Now i dismantled it and saw that the commutator gaps are full with dust... Brushes are in a good condition. I cleaned the commutator and now I will test the dynamo with your instructions that you sent me...

Hello!
I have a problem with my Ariel KHA 500 Dynamo. Maybe someone can help me. The Lucas Dynamo E3L commutator coils are connected with each other coils when i measure with the multimeter. Is that correct or is there a short circuit in the winding?
