 Posted: Fri Oct 12, 2007 1:05 pm Post subject: Ground loop risk? |
 |
|
I'm feeding my strobes from the 12 volt buss behind the panel.
Is it necessary to run the ground for the strobes back to the panel
ground buss, or can I just run the ground to the battery terminal
since I'm in that vicinity?
I'm trying to save a wire going forward.
Will I risk a ground loop if I have more than one ground termination point?
Thanks
Neil

What kind of airplane? If a metal airplane it is
perfectly useful to use local grounds for
landing lights
taxi lights
nav lights
pitot heaters
strobe power supplies
landing gear hydraulic pumps
etc.
These are ALL potential antagonists
for loading alternator noise onto the
airframe. But taking potential victims
to the single point grounds on firewall
and/or instrument panel as suggested
in Figure Z-15 of:
