I have what I believe to be a 1964 model Y 20 Yamaha.
It has a spot to mount a small 6 volt battery.
But the is no wires there to hook one up.
And I can not see were there used to be any wires that have been disconnected.
It is in great condition, and everything looks very original.
So I am baffled why no battery conections.
Does any one know about these little bikes?
Wiring diagram?
