Hi All,
I am building a hybrid moped - gas engine power to the rear wheel - 48v power to a front hub motor. It all works well except I am unsure of how to design the circuit for the headlight and tail light. The bike has a lighting circuit to power the lights - it also has a rectifier so the light uses 12v dc power. I have a 36w dc-dc converter to have 12v power out of the 48 v battery. I want to have the lights work on engine power only, battery power only, and also if both engine and battery power are being used - and all through a single switch. I believe I need a diode on the 12v output of the dc-dc converter, but don't know if I need one on the positive side of the lighting circuit. Is there anything else I am missing?
Thanks for any comments or help you can provide.
