The battery switch cannot be turned off when the alternator is started.
Otherwise, the current of the generator will have no outlet voltage and the generator will burn the diode of the generator.
So the right way is to turn off the engine generator and then turn off the battery switch.
The AFD function is that two screw pins can be connected to the field end of the alternator.
Before the battery switch is disconnected, the AFD screw foot will open the circuit and turn off the alternator.
That is, before turning off the battery switch, she will automatically turn off the alternator (through the two studs of AFD)
Avoid burning the alternator.
