(1) Turn OFF the power supply.
(2) Remove the connector (X106A, X107A) on the PCB to measure the resistance value.
Judgment criteria: resistance value between each phase is within ±20%
(1) Measurement of power wire connector.
Remove the X1A connector from the fan PCB (A2P) and measure the resistance
between the U and V, V and W, and W and U phases of the motor connector (with
five conductors) and check that each phase are balanced (within a permissible
dispersion range of ±20%).
(2)
Measurement of signal wire connector.
Remove the X2A connector and measure the resistance between GND and Vcc,
Hw, Hv, or Hu terminals of the motor connector (with five conductors).
