Three strokes make it easy for you to overhaul the electromagnetic coil failure reason

1. The electromagnetic coil uses the engagement and release of the armature to transmit power. The failure of the electromagnetic coil is secondary to the abnormality caused by the status disorder and the failure of the coil to form.
2, the electromagnetic coil status imbalance will make the armature measures abnormal. When the interval between the electromagnetic coil and the electric armature is too large, the stroke of the armature is large, and the suction is insufficient and the action is not taken: if the pitch is too small, a wrong action may occur. From the new adjustment status, it can be cut and cut.
3, the electromagnetic coil does not work the second time the coil is destroyed and burned, resulting in the armature does not move. This can be measured by a multimeter and its resistance value is infinite, which indicates that the coil has burned out. If the coil is intact, the holding circuit of the electromagnetic coil is faulty. This can be measured with a multimeter.

The input voltage of the electromagnetic coil. If there is voltage, the fault is stuck in the armature. Note that the filter is clean and free to make it free to move. If there is no voltage, the drop is in the working circuit.
