A 767 with a long history of intermittent faults:
Flickering lights on different occasions.

Pitot heat Korry Switch lights 
Flt data Recorder off light

multiple entries and replacement of equipment and harness 
PSEU unit accusing always sensor S267 R/H MLG
computer will switch from far to near  causing the lights flickering. 

On the Fwd E/E behind the EICAS computers, probably from the a last MOD found 3 clamps pinching wires on a big bundle. This problem has caused multiple AOG and money loss to the company.
Hours of T/S and man power unknown.
