Generator/ignition for Maico 250/400/440 (1976-77)
    
Magnet based generator with integrated ignition. Output at 12V/100W DC. Solid state ignition with own power supply from within the system.

Replaces stock Bosch Dynamo, regulator and ignition coils or the Kröber Magneto.
You have to fasten the ignition coil and regulator outside of the motor.

Engines the system is made for can be recognised by the fact that the rotor (flywheel) is fastened by a screw (and not a nut).
 
Please note:      
Is frequently confused with system 78 30 799 DC  which replaces Bosch Magneto.
There are engines where aftermarket the crank of the later 3-shaft Maico has been put - here the rotor will not fit.
