Mystery Electrical Component

[6352]

Now that’s funny John. Or maybe the breaker for the chute?

It is a Klixon CA-2 Circuit Breaker. 2 amp auto reset circuit breaker.

Thanks for the help everyone...

This breaker feeds the turn and bank switch in my airplane and has two other connections. I believe one of them goes to the stall warning system and the other I am unsure about. Need to do some more investigating.

Need to do some more investigating.

Check that green wire. It appears to be unfused. Circuits should be fused as close to the power source (that big wire with the solder taps) as possible.

John,

That green wire (why did they use green??) was feeding the strobe fuse holder. I replaced it since it was frayed at the fuseholder. I would have liked to have soldered the new wire straight onto the main bus but my iron didn't have enough heat. Anyway, the wire was and is indeed protected.

If you notice, there is a black wire which comes off of that auto-resetting breaker. It goes to the airplane-right side of the instrument panel and up the wiring channel ostensibly to the headliner. I don't know where it goes from there... a mystery... maybe to the old dome light which is no longer installed? The other wire that comes off of the auto-resetter goes up the left wiring channel and to the stall warning vane (I believe). Still yet to track that one down.

I am on the road until Monday so not able to do any work or figure out the answers to these mysteries.

The original airframe wiring was in excellent condition, but everything added to the airplane after the fact was done somewhat haphazardly. No shielding on comm wiring, electrical tape covering up soldered joints (where there didn't need to be joints in the first place). Found a wire nut with electrical tape over it... now gone and properly replaced by a solder sleeve.

The airplane has a 35A generator on it but the wiring from the generator to the voltage regulator and from the regulator to the bus was never changed so I ran new 10AWG to fix that problem. Yadda yadda.

I removed the old KT76A. I removed the inline fuse holders for the KT76A, KX155, and Cigarette Lighter.

Added a radio bus with 5 breakers on it fed from the Radio switch:

KX155
Stratus ESG
Intercom
Bose Jacks
Cigarette Lighter

The airplane didn't have an intercom so I added one and made up a new harness for it with properly shielded wiring.

I capped and stowed the PTT wiring from the intercom harness for the pilot and copilot yokes. That's going to be another 'project' that I'll tackle sometime soon.

As long as it's after the fuse it'll be fine!
