Looking forwards for your advice soonest

Hi Ramjam,

I have checked and found that the converter 1U06 was completely burnt out !!! I don't know why it was burnt out ? I have check the traction motor Resistor of each phase ~ 0.8 Ohm and couldn't find any causes to make the inverter burnt !! Please check and advise what I should check before installing the new converter in ?

Thanks & Regards
