LH & RH Marker Lights

[garyde]

I discovered my Marker and Signal lights on the Water bay doors are not working. Both sides, same problem, just on the water bay doors. I have tested the circuit breakers.
No power when testing to a different ground source.
From what I have learned so far the wires are seperate for each bay door. They go back to a terminal some where but I can not determine where. The wiring diagrams appear to indicate a middle Junction box but I dont know if that is right.
Anyone know anything about this wiring.
