The car uses two electrical systems. The original RC51 system is used with its stock alternator and a motorcycle battery to start the engine and run its functions. A standard auto size Optima rides in the passenger foot well and powers most of the other electrical requirements on the buggy. It is charged from an alternator powered at the rear axle. Two belts are used along with tensioners and an idler shaft. The pulleys are sized such that the speed of the alternator is increased due to being driveaxle driven instead of engine driven, where belt speeds would normally be faster.
