We've started wiring up Doug's Series A Comet. It has a BTH magdyno. When I removed the cover to attach the harness the only place that made sense at the time to attach the harness to the dynamo was to the stud pictured. The lead coming off of the brush of the dynamo, just visible behind the harness, has a red tag. The other brush, barely visible on the left has a lead connected to the case. Have I connected the harness to the correct terminal? I believe I have, but if someone with more experience knows different please let me know. Next question, in another thread I learned that as Series A Comets fitted with BTH magdynos did not have voltage regulators or cut outs to regulate the current the battery receives. It was suggested that a 10W diode would do the job given the lower power of the magdyno. Would the one pictured below be suitable? It is 10W 6.8V cathode cased Zener diode.
Many thanks
