I am adding extra alternator on my 912/100. Does any one have a wiring diagram of how to wire it? Two batteries? Two regulators? I have the book electrical connection but not sure on wiring. Should I use both alternator and a regulator set at 11.5 v so it will on charge a single Battery or batteries? Should I also use seperate switches for the mags? Do you use a 40 or 50 fuse in the main wire between battery and starter. Thanks
