Just wanted to follow-up on the resolution of this thread in case it helps someone else.
I reflowed the solder on the J106 pins and afterwards was getting continuity to J106-5 from TP7 and J107-6. Reconnected the board, voltage at J106-5 was 21V. All flashers work as they should.
Thanks again to @za...
