If you have a 2 stroke, Chinese engine, you didn't tell us what you have, the white wire will only produce about 6 volts and that is AC (alternating current), and a little less than 3 watts. That isn't enough current to run what you want. Overloading the white wire will shunt power from the CDI (ignition module) and shut down the engine. Go for a rechargable battery for your accesories.So you think that I vcant take power from engine ?
