Sorry to say so, but this does not sound right to me... (if these statements have been retracted in the meantime, I apologize for pointing to them "again")
The "charging system" on the V11 consists of nothing more than a voltage regulator (not a current regulator, as stated above). In Guzzi's case, it regulates to 14-14.6V on its own terminals (not battery). The voltage on terminals never exceeds 14.6V, If it does, the regulator is faulty.
Charging current is theoretically limited by the regulator's voltage, battery's state of charge (voltage on the battery with no load), battery's internal resistance (milliohms range) and parasitic resistance of the wires and connectors between the charger and the battery (also low ohm range), practically however it is limited by the alternator's/regulator's capacity.
Max current that the regulator can deliver is 27,5A@10k RPM (~400W). You will need roughly half of that to supply the regular load (150-200W), so not more than 10-15A will be available to the battery at any time.
Only battery can blow the 30A fuse, regulator cannot. If it's blown, there is a short southward of the battery/fuse.
Docc, where did you find that info on "battery priming"? Odyssey is quite explicit on "never exceed 15V" and their charger's documentation also does not provide any statements on high current/voltage spikes. Can you perhaps post a link to a document?
I know my comment is more than a year late and I sincerely hope it does not spur a flame war. This is definitely not the intention.
