My turbines aren't spinning. Why?

Generally, if standing outside while the wind is blowing the turbines should be spinning. If the turbines spin by hand but not in the wind then the bearings are probably too tight. If it's an internally braced wind turbine, be sure that the upper bearing is straight and tightly fastened to the crown plate (top plate) of the turbine. If it's an externally braced wind turbine, make sure that there is about 1/8" of the shaft showing between the top of the upper bearing and the underside of the brace plate (plate that the 3 external braces rivet to at the top of the turbine). In both cases be sure that the retaining cap on the bottom of the lower bearing assembly is snapped securely in place and not crooked.
