batteries.jpg Dual battery circuit for winch & power inverter with parallel isolation relays and indicator LED. NON-STANDARD WIRING - DO NOT USE THIS DIAGRAM FOR DIAGNOSIS!!! The aux.batt. switch positions are: Automatic (normal, aux.batt. is charged when the engine is running & provides extra reserve minutes when key-on, engine off); Isolate (aux.batt. is not connected to the alternator or main batt.); Jump-start (main batt. dead/gone, aux.batt. always connected). The 2-color LED can be RadioShack 276-0012 (2.8V 30mA) with resistor 271-012 (330 Ohm 1/8W). If it lights green, the aux.batt. is powering the truck; if it lights red, the aux.batt. is weak.
