Hi!
I'm trying to wire a 6v DPDT relay to switch between 2 power sources.
My application is going to use a bicycle dynamo (rectified/regulated to 6vdc) to power the lights - and powered by a 6v battery when the bike is not moving.
Can the same 6v coming from the dynamo be used as BOTH the switching voltage and the "other" power to the lights?
I want to power my lights from a 6v battery until the dynamo kicks in.
I have tried using 1N4001 diodes but I must be doing something wrong - I am having major power sucking issues - the lights come on very brightly at first, and then go dim very quickly (regardless of the power source).
Could someone please explain (hopefully with a circuit/picture) the correct way this should be wired?
Thanks!
