If you had the pattern below it calls out the M7162/7486

M7162 & M7161 = UDA50
M7486 & M7485 = UDA50A

      Error led MSD is the side to the front of the Ba11 (towards
the bottom of the boards.

      M7162 or M7486 M7161 or M7485

BA11-K

This points to a failure of the M7146 -- if the stuff is as I've
pictured. You seem to have them inverted -- or I misread your note.

Your pattern isn't documented as a valid failure code.
