Fig. 6. Electric wiring diagram of thte gen- 

 erator, battery, and winch motor circuits. The 

 light system and the other motors are taken off 

 the bus circuit, which is maintained at a con- 

 stant potential of 115 volts, as described in 

 the text. Coils represented by right angles are 

 resistances; those by acute angles are magnets. 

 The numbers connect the respective parts of re- 

 lays.
