I need help with the last phase of adding turn signals to my bike. As on the factory models, I want to run them off a battery (6V) which is charged by the 10W brake light coil. However, I would also like to use the battery to power my headlight when I am at slow speed or stopped at a light, since the 22W coil puts out zilch at that time.
WHAT I GOT:
a four coil magneto - ignition, 5W tail light, 10W brake light, 22W headlight
a set of turn signals that I am going to convert to 6V bulbs, hopefully LED to reduce power drain from battery
An electronic flasher unit designed for 6 or 12 volts
a 6V sealed rechargable battery (UB 645), rated 4.5 amp/hours
a handlebar switch for the turn signals, lights, etc
WHAT I WANT:
When the bike is up to speed and the magneto is putting out sufficient power, I want the brake light circuit to charge the battery. During this time I want the battery completely OUT of the headlight circuit, so the headlight gets full power and voltage from the 22W coil.
When the bike is stopped, the headlight gets power from the battery.
The turn signals operate off the battery at all times.
I'm not sure what I want to do with the tail light. Suggestions appreciated.
does something similar, but switches modes manually. I'd like a system that switches automatically.
You can see a wiring diagram for my bike on that link as well as how he added a battery into the circuit.
If anyone wants to figure this out for me, I'd be eternally grateful. It might help a lot of others out there as well.
