Claim:
A belt driven electric starter system comprising: a driving belt driven by a crankshaft of an engine; a starter generator affixed to a hinge point on the engine; two idle pulleys, one an inlet pulley guiding the belt to the starter generator, and another a outlet pulley guiding the belt from the starter generator, wherein a pivot point idle pulley that is the one of the two idle pulleys and a driven idle pulley that is the another of the two idle pulleys, are fastened together with the starter generator, and wherein the pivot point idle pulley functions as a pivot point for movement of the starter generator; a tension controller rotatably affixed to the starter generator and to the engine such that the tension controller extends and retracts in response to a force from the driving belt wound on a crank pulley fitted on the crankshaft of the engine; and a pivot point forming end for fastening the pivot point idle pulley; and a pulley fixing end fastening the driven idle pulley and being positioned higher than the pivot point forming end; wherein the pivot point forming end in which the starter generator and the pivot point idle pulley are fastened, functions as the pivot point for movement of the starter generator for extending and retracting the tension controller.
