Hi Dan,
Since there is just as much current flowing through the ground wire as
the positive wire, it is possible for it to heat up as well.

Use of solid wire is contrary to accepted practice
in all manner of vehicle. It's recommended for stationary
applications only.
Where is your panel ground bus located? Is it mounted
on or close to some panel support structure that is
not subject to periodic removal from the airplane?

Thanks, guys :-)
Sounds like I'll get some stranded wire for this. My panel ground is located on
the under side of the permanantly mounted glare shield. It's a few inches away
from the main buss block, whose piano hinge sections can be seen in the pic.
Regarding the panel ground buss, I have used a section of the B&C forest of tabs.
It would be convenient to rivet the brass block to the glare shield and use
one of the tabs to connect to the firewall. Would using a faston for 10awg wire
here be okay, or would it be better to solder it, or both? I'd rather not
have an ugly bolt head on top of the glare shield.
If I solder without the female faston, would I just drill a hole in one of the
tabs big enough for the bare wire to go through and solder it like that?
If soldering isn't as good as a ring to bolt connection, I'd prolly make a little
standoff bracket for the panel ground.
