| Subject: | Grounding through engine control cables. |
This excerpt from the Aeroelectric Connection Rev.12, Appendix Z, Note 5 reads:
"Even then, make sure that jackets for engine
controls do not ELECTRICALLY ground both a metal panel
and the engine . . . they can easily become a SECOND
ground path on the wrong side of the airplane and create the
same problems we're striving to eliminate."
Since my control cables touch the engine, firewall, and instrument panel/throttle
quadrant, the above statement seems in indicate that I need to insulate them
so as not to provide multiple ground paths in addition to the grounding strap
I will install from the engine to the firewall mounted grounding post (forest
of tabs).

Notice that note 5 begins with, "When the battery and engine are on opposite
ends of the airplane"
Is that the situation in your airplane? What is the make and model of your aircraft?
Engine cables are not insulated from the firewall or instrument panel in hundreds
of RV-12s.
Audio cables should only be grounded at one end, especially microphone
cables or other cables that carry signals which will be amplified.
