    197X Motobi 125 Main Switch Wiring

    I am helping my friend out doing the wiring on his newly restored Motobi 125.
    The only thing that's left before we finally can start her up is the wiring of the main switch.
    As you can see in the pictures this switch has 3 positions. Can anyone tell me what we are switching in those three positions and how the wires get connected?
    There are obviously the following wires to be connected:
    Batterie (B+ ?)
    Horn (T+ ?)
    Stop Switch (T+ ?)
    Magneto (FT ?) (it's a tow wire magneto, one wire obviously goes to the Hight Tension coil)
    Tail Light
    Power supply to light switch (56?)

    What is the blue wire that's on 57?
    Is there anything that goes to the unmarked clamp?

    Any help is kindly appreciated.

    problem solved

    Ok I finally figured it out

    Switch position and function:
    0 Stop light, horn, charging batterie
    II same as "0" plus tail light, position light in head lamp
    I same as "0" plus main light, tail light

    B+ Batterie plus
    T+ Power supply for horn, stop switch
    T- Horn minus, horn switch
    57 position light in head lamp (I think it says pin 4)
    56 power supply to light switch
    A (unmarked pin) magneto, Z-Diode in
    Coil solder spot Z-Diode out
    FT Tail light

    Hope this will help someone at some point

    Motobi Imperiale wiring

    Thanks for this info. It really helped me. I have drawn up what I believe to be the correct wiring based on my Motobi Imperiale 125 Sport 1960 model. Hope this in turn helps someone out there. Hopefully have attached the file?
