A20 actuator CR3 01-dc12v, after the customer test motorized valve body is in place, there is still

After the valve body of the A20 actuator is in place, the internal motor is disconnected and the current should be zero.

The A20 actuator, cr301-dc12v, has a current of 2.8mA， after the customer has tested the valve body in place. Why?

There's a circuit inside, there's a current. When the actuator valve body is in place, the switch has cut off the circuit leading to the motor. There is no voltage or current on the motor.
