1) Disconnect an terminal of voltage distribution resistor from each DC link
electrolytic capacitor
2) Set the multi meter to resistance mode, connect the probe to +,- terminal
of the capacitor. If the estimated resistance value is increase
continuously without short(value is 0), then the resistor is normal
3) Set the multi meter to resistance mode, confirm that the resistance value
of the resistor is around 270 kOhm
Check and replace inferior
