Compressor and Alternator Drive

Having examined the various options to drive the compressor and alternator to load the engine, there is not a way to do so and maintain the vehicle mobility without significant modification to the engine and cart. Because of this the best way to drive the two will be to chain drive the half shaft and then use a belt to drive both the compressor and alternator as below.

Sorry for the cartoon drawing but I didn't have access to CAD software.
