I had time to check the pcb today,
it appears the short is made through the cooling plate
mounted to the chassis. ???
should be normal i suppose,

There is suposed to be an insulator sheet under all the IGTB/ FET devices for this reason. If you do not have this, it might just be a simple matter of installing some.
