2638 No Powering. FC137 Propulsion Precharging resistor protection. ~~~~~ 2638 No Powering. FC137 Propulsion Precharging resistor protection.  #2638 no powering with FC137 Propulsion precharging resistor protection observed on TIMS. Checked pre-charging resistors and INV1 and INV2 ok. BCH IGBT found shorted Notification to HM for BCH c/o, ops20 for propulsion check after BCH c/o. Done by: Kamal, Kalees, Sateesh, Kumar 45417 2638 to Conduct no power test and limited movement after BCH change out   After BCH changed out by HM, conducted no power test ok; during limited movement, power fault recur. Further check found BCH wire GBT2N and GBT2P installed wrongly. Swapped the wires and installed correctly. Power test ok. No abnormalities observed during limited movement and depot shunting. Side finding Found air leaking from #2637 and #3638 MPV. Changed out both MPV. #2637 MPV Notification: 2596902 Old SN:   New SN: 35153028 #3638 MPV Notification: 2596904 Old SN:   New SN: 35144228 Done by: Jack/Koh/Rizman 45421
