What are some of the Battery Power Management Components for my GMC?
BATTERY COMBINER A combiner is an electrical apparatus used to permit two battery (banks) to be charged “intelligently.” The combiner relies on the fact that the voltage across a charging battery will rise as the battery charge increases. When the charging voltage is great enough, the combiner electrically connects both batteries in parallel to permit them both to become charged. When the batteries are not being charged the combiner electrically isolates the two banks. Using a combiner in place of the isolator that is original equipment in the GMC permits the electrical isolation (keeps the engine battery from becoming discharged) when you use the coach 12V electrical AND allows both batterioes to be charged when charging voltage is present. This can simplify the electrical system if you want to permit charging of the engine battery from the coach charger. BATTERY ISOLATOR – a diode based device that permits both battery banks to be charged from the alternator (and allows the alternato
