Disconnect the connector and measure the resistance value with tester.
(Normal temp.)
To item of How to judge whether remote control is good or bad of the Judgment
of trouble by symptom.
Measure the resistance value of each winding coil by using the tester.
(Under normal temp. 25°C)
Since judgment of DC motor is difficult on the single motor, refer to 10-5-1. (3)
