Bob,
OK. Maybe I understood more than I thought. What you wrote in your reply to me,
is what I thought was an antagonist (motor, strobe power supply). But in your
earlier response to Tim (the one that confused me), you said a fuel pump (motor)
and strobe power supply were not potential antagonists (hence my confusion).
What am I missing?

I cant just hit the local ground that is right there at the Battery near
these components. Is this correct practice? Id be tempted to use the Firewall
ground for the NAV and Fuel pump.

Sorry, they're not potential PROBLEMS . . . assuming that
the potential victims are corralled off on their own
ground system. After all the panel mounted stuff is
protected, you can do about anything you want elsewhere
on the airplane. While outlying devices ARE capable
of being antagonists, they are not potential victims
and will not interfere with each other. Let's hear
it for precise speech! Your diligence in the quest
is commendable.
