I am comming with new info. I managed to check all voltages and also to repair the 145V rail. Now I have all voltages, but it seems that at least one board is taking to much current. In a minimal configuration I have checked the current consumption for each board. The thing is that I don't know the total power consuption for A+13V rail. After I have inserted A45, A48 and one A46 (a+b) I observed that the consumption increased from 0.74A to 4.26A which is quite much for 4 boards. Do you know how much current should I have on these boards?

Have a nice day.
