Hi Tango,
having two separate “boxes” for regulator and rectifier is a speciality of the B1 and B2 models, so that is correct.
Having non-isolated plug connectors within the battery charging circuit causes goose flesh to me !!!
Connecting the MINUS to the frame is ok, but source of electrical energy is the alternator in the motor casing. In the end there must be a good electrical connection also from the frame to the motor casing.
Not sure if the cables connected to the 3-way plug needs a special order or can be plugged in anywhere?
Attached two pictures of the Z750B2 electric as I just bought it.
Cheers, Michael
