Posted: Tue Apr 15, 2008 7:01 am Post subject: Tail Nav Light Ground

I’m wiring up the tail nav/ strobe light in the lower fiberglass rudder fairing for an RV-7. Is there any reason I can’t tie the nav light ground to the strobe ground? For the tail light, this seems to be the easiest option but wasn’t sure about the voltage running through the strobe. It’s either that or run a wire into the aft fuselage to a local ground.

   You don't want to cause an unbalance of currents

   to flow inside the twisted trio of strobe wires.

   The physics that make this wire an effective constraint

   on coupling of noise depends on integrity of combination

   of balanced currents and shielding.



   The separate ground wire is called for.

I just faced the same issue.  I chose to run a separate ground from the Adel clamp holding the rudder cable.

 

 It also took a bit more effort than expected to get a single lug #4 platenut in there to hold the Whelan.  But it worked well.
