Dear Bob N,
Because I have a removable instrument panel, it seems to me that it
might be a good idea to have a forest of ground tabs on the engine side
of the firewall and the other set affixed to the instrument panel proper
with a heavy connecting wire between them.
If I used say a 10 awg wire to join the two over a distance of about
300mm, would this be likely to give rise to the dreaded ground loop ? I
imagine not but I am not really sure hence my call for confirmation or
otherwise.
Your assistance is much appreciated as always.

Have you looked over the Avionics (panel) ground
bus architecture proposed in the latest revision
to the 'Connection?
This gathering of all panel grounds into a simpler,
lower wire count extension to the firewall sounds
like what you're wanting to do. See:

Many thanks
