A couple months back I was having issues with my gear warning breaker popping during actuation and I started fiddling around with my annunciator panel out of curiosity. I didn't disconnect anything, but I took the face plate off and moved it around before putting it back together. Somehow that fixed the gear warning C/B popping (so something was shorting out before) and the test button fell off because the solder was apparently worn out at this point. 

I can pull it out and get it serviced, but I'm wondering if there's something simpler I can replace it with. Is it just a panel of lights? It seems like a big box just to do that, but ideally I could put something with LEDs in there and never have to worry about bulbs.

It's an IAI panel, model number A8/1000H.

So the annunciator panel for the most part are just lights that come on with a +ve voltage signal.  But some of the circuits have some 'smarts' to them - the annunciator panel is calibrated to the fuel level to give a low fuel warning.  And the alternator either comes on for OV or flashes for under voltage.  And the vacuum does something similar.

I have a JPI that generates the same or similar 'warnings' and have replaced the rest with Eaton annunciators (not cheap).

The only thing I use mine for are the gear related annunciators. I have a g500txi with eis and so vaccuum, so I don't think there's anything on there that matters too much other than the gear related ones. 

 

What are the Eaton annunciators?

Here's one I had made.  But for a Mooney I had another one made with red 'unsafe' and green 'down' in a horizontal split.  Also Alt 1 and Alt 2 in a vertical split.

About $180 for each lens made up, and if you shop around you can find useable bodies for under $200.

Probably the simplest thing to do is get it serviced.  @Ludwig  Ludwig& Associates in Addison, TX. took over the servicing of all International Avionics Inc. (IAI) products earlier this year. 

The old IAI website is still up but the phones don't seem to work any more.  International Avionics Inc. | Manufacture, Sell, Repair

Contact info for Ludwig is in the post below and  phone is 972-616-0101

When I did my panel upgrade I removed the annunciator panel. I no longer have vacuum, so that light is gone. The G3X can provide a number of other alerts. I had warning lights installed for the other needed alerts - see photo: IMG_5729.jpeg.aa9c45336f9dbddf4c336965bedc5ef0.jpeg

54 ppm CO seems a bit high for an in flight number.  Have you looked into that?

Looks like the red annunciator light below the gear down light is on as well, can’t read the label of what it is.
