The National Luna Ignition Sensor Cable is an optional accessory for National Luna DC Power Packs. It plugs into the Ignition Sense Port on the face of the Power Pack and lets the unit charge reliably in vehicles whose charge voltage runs low or erratic — common on modern "smart alternator" systems. If your alternator already holds a healthy voltage, you probably don't need it. Key Features Enables ignition-sense charging: Lets the Power Pack detect when the engine is running so it charges correctly on smart-alternator vehicles. Simple two-end hookup: Small end into the Ignition Sense Port, large end into a socket that's live only with the ignition on. For low-voltage systems: Best where alternator output sits below 13.2V under normal driving conditions. Specifications Length 8 ft Connects to Ignition Sense Port on National Luna DC Power Packs Best for Smart-alternator vehicles with low or erratic charge voltage SKU CON-00202 Compatibility Compatible with National Luna DC Power Packs fitted with an Ignition Sense Port. Plug the small end into that port and the large end into an ignition-switched 12V socket. Caution: connecting the ignition override to a permanent 12V source can over-discharge the main battery. Only use the Ignition Sense feature when the vehicle's alternator voltage is below 13.2V under normal conditions. Browse the full Eezi-Awn line for more of the overland power and camp gear we carry.
