 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.  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.
