A mounting system for mounting a supplemental alternator, as well as methods of assembling the same, is provided. The mounting system includes a top mounting bracket that is configured to align with a top flange aperture of the additional alternator. The mounting system also includes a bottom mounting bracket having a bracket aperture that aligns with an aperture of an existing alternator mount and also having a flange aperture that aligns with the foot flange aperture of the additional alternator. The mounting system further includes a shaft that couples to the additional alternator.

A power supply system includes a regulated power source that has an a synchronous machine, a flywheel with the shaft connected thereto, an electrical generator electrically connected through a switch to the synchronous machine of the regulated power source, an engine having a main shaft coupled to the shaft of the electrical generator, a power supply, and a switch connected between the electrical generator, the power supply and the regulated power source. The switch transfers power from the regulated power source to the electrical generator so as to cause the electrical generator to rotate the shaft in order to rotate the shaft of the engine during engine start-up.
