 ====== Alternator charging ======
+aka Split Charging for our European friends
 In a dual-battery system((starter battery and house battery)) some of the alternator output is used to charge the house batteries when the engine is running.  When the engine is not running **the house battery is electrically isolated** from the starter battery to keep from draining it and leaving you stranded.  So the devices that handle the isolating/combining duties are called //battery isolators//.  There are several different types.

-Power from the alternator is shared with the house battery using an isolator of some sort.  This allows the [[electrical:12v:intro|house battery]] to charge but does not allow the house battery to pull power from the starter battery.
