A 6 volt generator will develop a lot more than 17 volts. I have run them unregulated on a test stand and watched them turn over 30 volts. The problem though is that this higher voltage in turn sends a much higher amperage through the field coils. It is the regulators job to handle the current in the field coils to regulate the voltage output of the generator. A regulator cannot reliably handle more than about 2 or 3 amperes max without excess arcing and burning of the points. This is one of the main reasons todays regulators life is so short as the generator is not properly matched to the regulator or visversa. We sold a new 706 gas and it had regulator problems immediately. Second regulator shortly failed so further testing showed field coils were actually 6 volt and too low of resistance. New field coils solved problem. Many old 3 brush generators with high, low charge controls have very low field coil resistance, thus high current flow through fields so when you team that generator with a voltage regulator, problems are imminent.
