Also I checked sector one it is working, i saw signal in all the channels that are connected to the "Dawn" VME. I debugged sector5 's board that has a guard current, none of the boots is responsible for the for the guard curent, as all of them are out of the board, the guard current is still there, the only way to get rid of it is to separate the guard's jumpers from any side of the board. I checked the resistors of the board, they all good.

Turned off HV and torqued down all mounting screws. Some do not appear flush against STB/HVB surface, but most are flush. Turned back on HV. Guard current is still 0.280 microamps. Torquing screws didn't fix it.
