RESISTER CHECK
Use an ohmmeter to measure the resistance
between the terminals. Check that the measured
value is at the standard value.
Standard value:
BLOWER FAN AND MOTOR CHECK
When battery voltage is applied between the
terminals, check that the motor operates. Also, check
that there is no abnormal noise.
