Thanks Bob, that is where I was heading. But it seems odd that the wire pins to tray buzz on the ohmeter. Must be doing something wrong.

The label "NAV SWITCHED 13.75VDC" says that this is
indeed a power output pin controlled by the nav receiver's
power switch. There is a Note 7 associated with this
path:

. . . which tells us that this ouput is limited
to 300 ma.
Probing this pathway with the voltmeter should show
bus voltage with the nav radio ON. This power
comes from the radio and is switched internally
to the radio. If the power is missing on TWO
radios, then it seems likely that the disconnect
is somewhere in the ship's wiring.
