Voltage regulator cross-references - Magneti Marelli electronic
Moto Guzzi V700, V7 Special, Ambassador, 850 GT, 850 GT California, Eldorado, and 850 California Police models
Originally, Moto Guzzi fit a mechanical Magneti Marelli voltage regulator.
Thanks to Dave Pinchard for making me aware of this electronic voltage regulator applicable to Magneti Marelli charging systems. Dave reports that the A.P.E. unit has been working well on his 1971 Moto Guzzi V7 Special.
