Can determine voltage several ways: If the electrical system has only a cutout (usually mounted right on the generator) and no regulator, it's 6 volts. If you've got a voltage regulator, often the regulator voltage (and sometimes polarity) will be marked on the cover. Or if you've got headlights, pull one and look at lamp - voltage will be marked, or can be crossed from the lamp number. If you've got an alternator 12 volts is virtually assured. If all the above fails, you can fire the motor, and you have a voltmeter, try this: Run the motor at 1/2 throttle and measure the voltage across the battery cables. About 10 volts or lower means 6 volt system, 14 or higher says it's 12 volts. Ground polarity can be determined by hooking up a battery then turning on an electrical load (lights or ignition) without starting the motor. If the ammeter deflects toward "-", you've the battery ground polarity correct. If it reads "+", you've got it backward. Finally if you have an alternator, it WILL be negative ground.
