Understanding And Maintaining The BMW /2 Electrical System

[BMW-Guzzi]

This manual was written to help owners of /2 BMW motorcycles to service their bikes and keep them in running condition. When these motorcycles were made, they had very different electrical requirements to motorcycles today, and used equipment which today’s owner may not fully understand. Doug and Kees hope that this manual is useful to owners of these motorcycles and that it will help owners keep their bikes where they belong – on the road.
