How it works?
When the engine is running the 'Charge Guard' senses the voltage and allows the charge through to the Auxiliary battery. When the engine is switched off the 'Charge Guard' senses the voltage drop and separates and isolates both batteries. This means that equipment powered for the auxiliary batteries cannot drain the starting battery
Why you need one?
With today's engine management systems and 'intelligent' alternators you cannot use the charging light on the dash as a switch, also you cannot jump start most new vehicles without the danger of damaging the engine ECU. This unit then becomes cost effective.
Who needs them?
Emergency and Utility vehicles where battery drain is a problem, where multiple beacons/work lights or power tools are being charged
