Rear Dynamo

Postby timmitchell » 31 Oct 2017, 3:44pm

My Genesis TDF has a B&M Secula Plus tail light...which doesn't work. The headlight does, so I assume the dynamo is fine. I have taken out the connections and reconnected them but still nothing. Any ideas???

have you tried reversing the connections to the rear light?

To diagnose the issue try connecting

- the generator directly to the rear light using short new wires (but just to test, don't run it at speed) and then
- the generator directly to the rear light using the wires on the bike and then
- via the connections in the headlight

this should pinpoint the true location of the fault.

cheers
