I am building an all wood electrically dependent aircraft and the plan is to 

use, essentially, the Z-19 RB wiring scheme.  What are the thoughts on the 

ground wire?  It will be a "Fat wire" going from tail section to the 

firewall.  It is a single wire, and single point of failure!  Should I 

install this single ground wire making sure it is done with the utmost care, 

and say these cables never fail and forget about it, except for regular 

inspections to insure its integrity, or should I add a parallel ground, 

somehow, to keep my electrically dependent engine purring??



Thoughts, suggestions, please??

   Fat wires are generally considered as robust as

   prop bolts and wing struts. Of course, weak links

   come in choice of hardware and installation technique.

   However, using 5/16" or larger hardware torqued to

   recommended values and reasonable care in installing

   terminals will cover you nicely.
