Module: TM4 
Target/Number:  
Subject: TM4 steerers staus after" left " grounding issue, and first stage investigation 

Left (short) is switched with bottom. So on module:

"Top" is still top.

"Left" is bottom in module actually

"Bottom and Right" is Left and right in module actually.

 For the connection in ITE:

Left  cable is connected to "left" ( bottom  in module actually)

Top cable is connected to " Bottom and Right"( left and right in module actually)

Bottom and Right cable is connected to "Top" which is top in module.

Frank and I removed the panel, disconnected the "Left"cable  inside panel,  and checked  cable to ground resistance. "Left "is dead short to ground on ohmmeter check still. So the short could be on cable or inside source tray.  Further investigation is planned to confirm the short  location.
