A brushless alternator has a housing with a front portion and a rear portion. A stator assembly, rotor assembly, and coil support are positioned within the housing. The coil support has a shank portion of a first outer diameter and a base portion of a second outer diameter greater than first outer diameter. The base portion includes a plurality of air flow openings that extend through a second sidewall. A rectifier and regulator assembly is positioned on the outside of the rear portion of the housing. A front fan circulates air across the stator assembly at the front portion of the housing. A rear fan creates a cooling flow of air through flow openings of the coil support to circulate air across the regulator and rectifier assembly and the stator assembly.
