Type: Standard Operation 
Module: TM3 
Target/Number: no target 
Subject: Electrical check 

Electrical check was performed on TM#3 with no target nothing was wrong was found, but our megger does not go above 1000 volts so any problems above this value would not be seen, see attached pdf for details.

Also the 55 pin(top) double 9 pin (bottom) connector was tested as well. When it was meggered to 60kV common more then 50% of the lines failed, when those line were identified with a resistance package two were unable to be indentified. The wiring for this double 9 pin connector should be removed to prevent HV problems. New wiring is not physically possible to re-install in its place, see the PDF for the wiring details.
