Fitting instructions for automatic alternator controller
for Moto Guzzi with Bosch alternator
1. alternator modification - 2. Fitting - 3. adjustment (ignition only)
First remove the connector block of the alterator stator coils and the Y-connection. Don't cut the wires at the connector block, only unsolder them! With the Y-connection also the screw must be removed. Also unscrew the terminal lugs at D- and DF.

 

To avoid a short cut please file off the right half of the Y-hole flange.

 

Then put the printed circuit board onto the alternator and fix it with two nuts and toothed lock washers at D- and DF. At the ground connection put a 6mm nut as a spacer between the printed circuit board and the alternator housing.

Secure the all srews and nuts with toothed lock washers and coat all contact areas and screws (also the 6mm nut) with battery pole fat!

Finally solder the stator wires to the terminal pins very accurately (which wire on which pin doesn't matter), fasten the Y-connection to the corresponding terminal with the 5mm screw.
