What if the truck regulator is burned?

When the regulator of freight car is burnt out, remove the wires on the magnetic field column in time. When it is judged that the regulator is damaged, the wire on the magnetic field terminal can be removed, and then a light bulb of about 10cd can be connected between the magnetic field terminal and the armature terminal, so that the magnetic field current can form a loop through the light bulb to limit the magnetic field current, which can not only make the generator charge the battery and supply power to the outside, but also prevent the generator from overheating and damaging electrical equipment.
