Maybe I understood more than I thought. What you wrote in your reply to me, is what I thought was an antagonist (motor, strobe power supply). But in your earlier response to Tim (the one that confused me), you said a fuel pump (motor) and strobe power supply were not potential antagonists (hence my confusion). What am I missing? > Quote: > So I left my Aerolectric book at work and have a quick question. > Composite A/C, rear engine, Battery. > IIRC, I will need to run power and ground runs to the Strobe power pack, Fuel Pump and Nav lights, the grounds running all the way back up to the panel ground. I cant just hit the local ground that is right there at the Battery near these components. Is this correct practice? Id be tempted to use the Firewall ground for the NAV and Fuel pump. > > These devices are neither potential antagonists > or victims.

Sorry, they're not potential PROBLEMS . . . assuming that the potential victims are corralled off on their own ground system. After all the panel mounted stuff is protected, you can do about anything you want elsewhere on the airplane. While outlying devices ARE capable of being antagonists, they are not potential victims and will not interfere with each other. Let's hear it for precise speech! Your diligence in the quest is commendable.
