A rewire is absolutely on the to-do list! In addition to the questionable factory wiring, it's a mess from decades of retrofits. I'm just trying to stop the bleeding for now

I do see that in the IPC now, thank you for the help!

Can someone identify the circled component? It's inline between the master and avionics switches, but I'm not finding any mention of it in the wiring diagrams. I'm trying to chase down a voltage drop, and this seems to be contributing.

There have been some more developments and all hope is not lost. Give me a little time to tighten up the loose ends and I’ll report back. Any updates? I've reached out to Flight Resource to see if they have any performance data for the MT 80" Ultra on the C145/O300, and what they thought about...
