My Magneto
You're right, Dix - most of the time.
This bike's magneto has 3 coils feeding 3 independant / seperate circuits:
1. Ignition coil - makes the spark that maked the engine go round. Not affected by battery, etc.
2. Battery charge coil - gets rectified to charge battery. Battery feeds horn & brake light.
3. Headlight coil - originally feeds AC (mine now has rectifier) to headlight & dash lights
My dash lights are long gone, but I can't believe that they would make enough load to save the headlight !?? I don't understand how this worked when new? Maybe the turn signal lights - also long gone - gave the load to save the headlight?
The good news is that I've driven my bike a lot by now and the headlight (with rectifier) has not burned out. Last night, I drove it after dark and there was plenty of light to see where I was going, so it looks like I have a permanent fix...
