Servo Motor Winding Resistance Check
Figure 3-7. Servo Motor.
1. Disconnect the servo motor connection from J2 on the MPCB.
2. Using a standard ohmmeter or multimeter, connect the meter
leads to the two wires going to the motor.
3. While manually rotating the servo motor, monitor the
readings on the meter. The acceptable range is 4-10 ohms.
Typically, the reading is 5-8 ohms.
5. If the measurement is found to be unsatisfactory, replace the
servo motor.
