Voltage regulator cross-references - Bosch electronic
Moto Guzzi V700, V7 Special, Ambassador, 850 GT, 850 GT California, Eldorado, and 850 California Police models
Updated:
Originally, Moto Guzzi fit a mechanical Bosch voltage regulator. While not original, the Bosch electronic voltage regulator is an excellent choice when a replacement is needed.
Thanks to Dave Washburn and Charlie Mullendore of Antietam Classic Cycle for providing this information on the old Yahoo! Loopframe_Guzzi news group (which has now moved to Groups.io). In Charlie's own words:
...bike also needed a voltage regulator and I've had less than stellar results with the usual AutoZone/Advance Auto Parts supplied units for Bosch generators. Had two fail within the first month of use. This time I decided to use the same Bosch electronic voltage regulator: (Part Number 111903803D) I installed on my ‘72 Ambo
Sophia. It's been on there for three years with zero problems, begins full output at a lower RPM than the mechanical units and actually costs about the same.
This voltage regulator is available from MG Cycle.
