The Mean Green High Output Alternator is the answer to all of your charging problems. The Mean Green Alternator provides up to 300% more power than stock and can charge any engine, no matter what its' power requirements. The Mean Green Alternator's tool steel rotor shaft is supported at both ends by heavy duty double sealed bearings. Even the heavy duty solid copper starter windings are sealed with high temperature insulation. That's one reason Mean Green includes a 1 year Warranty at no charge on every alternator. Another is the heat resistant, multi-function integrated regulator which continues to operate even at extreme temperatures.
