Shorted battery is hard to find, it may be from a lead flake between plates. Considering whats happened, Id replace the battery.
With the aid of Gates Engineering,I offer this advice on external alternators driven from cam belts (I assume its off the cam). This risks a broken belt and engine damage.
beware of external alternators driven from the cam belt, the belt is at the point of being overloaded at low speeds by the addition of the alternator load depending on camshaft horsepower.
Unless the kit was designed by a Mechanical engineer or a very good mech designer that can calculate cam torque (a difficult thing to do that requires Calculus) , that "L" series belt might be overloaded on idle and break. Just becauseit hooks up and works electrically and mechanically doesnt mean it wont breaka timing belt.
Any such mod requires calculating belt tension (again, not easy) and changing the idler spring to compensate so the belt tension is proper to handle the additional horsepower load.
If this has been taken into consideration and calcs have been done to verify the belt wont break, and water cant get into the belt cases, then go for it. Electrically the bike wont care.
