Method and apparatus for eliminating power drainage in power sources used with starter-generators

A key actuated starter-generator circuit comprising:

• a key switch with a plurality of predetermined positions to provide a connection between an electrical power source and the solenoid;
• a solenoid to provide a connection between the electrical power source and a starter-generator;
• and
• a bypass rectifier to prevent inadvertent drainage of the electrical power source when the starter-generator is stalled.

A starter-generator circuit comprising:

• a multiple position switch operable to be coupled to a power source;
• a relay coupled to the multiple position switch, having a switching element, and operable to be coupled to a starter-generator;
• and
• a rectifier coupled in a parallel circuit path to the switching element to prevent inadvertent drainage of the electrical power source when the starter-generator is stalled.

A starter-generator system comprising:

• a starter-generator;
• a voltage regulator coupled to the starter-generator;
• a multiple position switch operable to be coupled to a power source;
• a relay coupled to the multiple position switch, having a switching element, and operable to be coupled to a starter-generator;
• and
• a rectifier coupled in a parallel circuit path to the switching element to prevent inadvertent drainage of the electrical power source when the starter-generator is stalled.
