You do not want one that outputs more than 14.5v. The above one is rated at 30amps.
Being an electrical idiot, can some one commit on what 30 amps is referring to? I am assuming the max rating of each of the stator output wires. I know some of you have measured stator output on the F800, what are the the readings.
Can't find a source for what effect on Canbus this may have, any thoughts?
In terms of power rating, 30 amps is roughly what we would need, the charging system on the F800GS is spec-ed at 400 watts - watts is Voltage x current so at (say) 13 volts, 400 watts is indeed ~30 amps.
Nice article here that explains how crappy shunt regulators (wait ... I meant "cost-effictive" ) differ from the more advanced designs (see the section "Active regulators").
One key thing I think we should all be doing is making sure that the frame/ground connection to our regulators is clean and solid ... if not, the regulator will quickly fry.
Other than replacing the regulator with a more advanced design, or somehow improving the stator windings or keeping them cooler I'm not sure what else we can do...............
