[[File:Twin Otter electrical system scheme.jpg|thumb|400px|The electrical system of the Twin Otter in a schematic representation]] | |||
The electrical system is fed by an 40 ampere-hour battery and two engine-driven generators (which operate as starter-motors when starting the engine). It is primarily a 28 volt, direct current (DC) system, but some components need alternating current (AC) to work. | The electrical system is fed by an 40 ampere-hour battery and two engine-driven generators (which operate as starter-motors when starting the engine).
