2532 Propulsion fault during depot shunt ~~~~~ 2532 Propulsion fault during depot shunt     Check INV1,INV2,BCH,BRE-ok.Precharging resistor ok.Conduct sequence test ok.Conduct propulsion no power test-satis.Limited movement found T/M #4 flashover. Not: 2335019 raise to RSW for T/M 4 c/o. Checked by Zulq/Asruddin. 25/11/21 2532 Propulsion fault investigation Conduct joint investigation with OE.Checked and measured M25,26,27(UVW for TM1 & TM2 )not shorted to ground-megger test ok.Checked and confirmed M35,36.37(UVW for T/M3 & 4)Shorted to ground.Measured INV1 ,INV2,BCH-ok.Checked HB,L1,L2,K connection ok.Found L2 and K contactor t signs of arcing-rectified ok.Conducted gate test-ok. After RSW T/M change out,raise 0030 to follow up with no power test to confirm if there is abnormal voltage/current to T/M. Done by Athur Sam/Lim J. H.  26/11/21 2532 Propulsion no power test after RSW TM c/o Carried out proplusion no power test,satis.Limited movement satis.Depot shunting movement satis. Checked by Joshua. 28/11/21
