If you connect both to the permanent 12volt IT WILL NEVER TURN OFF TILL THE BATTERY GOES FLAT Yes there are opinions both ways and only one way is correctĬonnect it any way you want The way I posted is the correct way from the instruction manualĪm well aware of what the Power Magic does having used one for two years. It is quite difficult to test, as you would only know that it works if the battery voltage actually drops enough to trip the circuit to disconnect the camera power.
has anyone actually tried this? does it work? I dont beleive that this would have anything to do with the ACC connection - it's just monitoring the supply (BAT) connection voltage, but it might use the ACC going to 0v to switch on this function. However, there is also another function to the power magic pro, which kills the camera power if the supply voltage drops below a preset voltage e.g. The power magic unit will kill the power to the camera after the timer expires. If both the ACC and BAT wires are connected to permanant live 12v (Batt connection), then the unit will think that the ignition is always on (12v constant on ACC connection), therefore the timer will never start - it's the ACC line switching off that starts the countdown timer. From the replies so far, it seems there are opinions both ways.
