Help Identify this Electrical Component
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.

Looks like a Klixon CA-2 self-resetting breaker (the -2 is the amperage, that part may be different). You don't say what model you have, but in my '48 the IPC shows the breaker on the turn & bank. On the later models I believe it also protects the stall horn. Everything else on the the '48 uses fuses, shown in the wiring diagram as a wavy line. The breaker is illustrated as a semi-circle.

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

Re: Help Identify this Electrical Component
If you have a voltage drop it’s normally a loose or dirty connection or a extra heavy load . Having a close look at your photo it seems that some of your wiring should be replaced . Some of the insulation has worn through and is obsolete. You can’t let the sparks and smoke out of the wiring .

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

Re: Help Identify this Electrical Component
Some of the aircraft wiring I have seen makes me cringe . Auto and house hold wiring used and all sort of terminals used. Often it looks like a birds nest that a bird has rejected . Good /legal and safe wiring is as important as any balanced flight control. originally when i purchased my aircraft I found strips of copper sheeting running around between terminals and being wrapped in electrical tape . The original owners were trying to creat buzz bars between the fuses . I should have weighed all the rubbish that i cut and removed from my aircraft . Originally my aircraft had HF radios, UHF and IFF valve radios fitted where the back seat should have been . My aircraft spent some time in SE Asia for the US government . The “glove box”area was some sort control panel inserted .
