====== Chassis power ======
**Chassis power** is the 12v system used to start and run the vehicle.  Generally this system is completely separate from [[electrical:12v:intro|house power]] unless the [[electrical:12v:alternator|alternator is used to charge the house batteries]].

For our purposes the main components of the chassis power system are:

  * the **starting battery** - a "thin plate" battery suitable for short duration and high current uses like starting an engine.  
  * the **alternator** - which creates nominal 12v power when spun by the engine.
