In this tutorial the moss motors tech gurus show you how to polarize a generator at the generator. Polarity of the generator must be set to match that of the voltage regulator. A generator unlike an alternator can run off both positive and negative current.
First unplug the voltage regulator and see if the engine shuts off with the key as normal. Do a check of all ground connections and a voltage drop test across the battery cables. How to polarize a 12 volt generator. Failing to polarize a 6 volt regulator can cause damage to the entire electrical system of a vehicle or machine.
