Electronics parts will fix your overcharging for ever. Remember the guys who ran with the additional center light in the grill? That was to keep from overcharging. Now, look up a zener diode. This little component has a set voltage built into it in many voltages. Install this device on the output cable of your generator weather or not an A.C or D.C. generator & it will shunt the extra voltage. Go for a 13.8 voltage & it will block any extra voltage the generator builds. I looked them up in Radio Shack & they are described as; Gas tube surge voltage protectors. Used for overvoltage protection with high current capabability, three electrode types, including fail safe & vent safe options. This gives a guy a base line to start with. It basicly blocks any overvoltage & lets any voltage below the set point to pass. It is a raw form of regulation that will stop over voltage curing the issue at hand. For questions go to a genny rebuild store, they know what will function.
Good luck!
