As Dave pointed out, the metallic enclosure
of your splitter has continuity to ground
by way of the coax shields that are tied
to it through the connectors.
Things that go on 'inside the wall of shields'
in a feed line system is pretty much an isolated
world. Just how and where the shields get tie
to the airframe . . . or whether they ever get
tied to airframe has no influence upon the
business of getting radio frequency power from
one end to the other.
Are you seeing similar symptoms with more than
one steering needle? Both VOR or is one of them
a Glide Slope?

Had a little hitch in the assembly task. Found a layout
error on the board and some scrambled numbers in the
connector pin-outs. All has been fixed, a board stuffed
and static tested. The SOIC-8 mos-fets will sink 1.5 amps
with no more than 0.040 volts drop. Higher currents will
be proportionally higher but still quite satisfactory to our
needs.
The revised data package and pictures are posted at:

I'll mail you a proof-of-concept board, test harness
and enclosure to work with on Monday.

Will this gadget replace the simple automotive 3 terminal flasher I'm using now
for Wig/Wag? I assume it's going to have timing options or something that makes
it better than a flasher.
Thanks, Tim

This project was conceived as an alternative to
the automotive 3-terminal flashers that don't work
well on LED landing lights.
As you can see from the wiring diagram in the
data package that the control switch doesn't
carry lamp current . . . so it can be a minature,
low current device.
We hadn't talked about timing options. But there
are a couple of extra inputs to the board that
could be used to select flash rates.
