Re: Generator voltage high ?
The battery controls the voltage in the system on a 3-brush. A model A generator will put out 12-volts if you use a 12-volt battery in the system. This is what makes it important that the battery be in good condition and the connections to it be clean and tight at every applicable location. You might want to get he battery load tested. It may have a problem developing if all the connections are good to go.
The generator may have brush wear or armature problems lurking in there.
2-Brush generators were actually regulated so they were set at 7.1 to 7.2-volts. It doesn't work that way with 3-brush generators. Voltage can be lower or higher than that depending on where the third brush is set.
