1. I've installed LEMO plugs for the headsets and need to feed them power. I would like to run it through the ACM for circuit protection. Is there a pin I can do this from? If not, I'll just go to the power lug on the ACM and use an inline fuse.


This does not need to be run outside of the ACM. When we build a harness with Lemos we will tee off from the main power going to the audio panel:

While it would have been easier to build the harness upfront with lemo power, it is not prohibitively difficult to modify the harness as-built to add the power wire. If you want to modify the harness yourself, have at it. Since you are local, if you bring the harness back to AFS we will happily add the power wires ourselves.


2. I have all of the components installed and will soon have all of the wiring done aft of the firewall. It's on the rotisserie, so no engine, master relay, starter relay, or battery. The wings are not on, so the only AHRS data will be from the G5. I have a 30A 14.4V power supply...can I connect the power supply directly to the ACM to do some testing?
This is fine and it is precisely how we test panels built at our shop, minus the rotisserie.
