This If it cant justify itself in dollars and cents, does it justify itself -981 Consult a parts professional for additional wiring information! When the time comes to crank up your generator, you will need to turn off the switch that goes to the R terminal. If the switch is on, the generator will try to output voltage while you are pulling the starting cord on the motor. You will find that it will be nearly impossible to pull the cord! If the switch is off, then there is little to no resistance from the alternator. In our prototype shown above, we used an 8 pulley with a 3/4 shaft, and key way. What we found was that the gearing ratio was less than ideal. We have run additional tests, and determined that a 4 or 5 diameter pulley is correct for this application. Either a 6 or an 8 will work if you cant find a 4 or 5, but you will notice that the motor speed decreases as a load is applied. To compensate if using a 6 or 8 pulley, the motor speed would need to be increased prior to a load being turned on. With the 8 on the motor, and the motor set to idle, we were able to kill the motor when a 150 Watt load was applied. If the motor speed was set above idle, there wasnt much of a problem, but the alternator was spinning much faster than is required. A 6 pulley under the same conditions resulted in a slight motor speed decrease when the load was applied. The alternator speed was about right. But when a 4 or 5 pulley was used, there was no motor speed change for the same load. In fact, it handled the load while running at idle speed, and turned the alternator at a speed more like found in a car.
