Aaah, OK. That makes sense now; thanks. I'm glad you found a definite cause for the problem and got it solved!

...the engine monitor is not receiving GPS data and the ELT gps reception test does not indicate data in (led connected to test lead).
I've been silently following this since you've been getting gre ...

I don't know if these will be helpful, but I was able to find a couple of documents related to this regulator or units like it.

First is a Textron Aviation service bulletin, SEB-24-06. It doesn't ...

I have several prototypes for recent projects on my bench that are excess to requirements. I'm offering them to anyone who wants one. Prices reflect my cost for circuit boards and components (no lab ...

This project is a low voltage warning module based on Mr. Nuckolls' AEC 9005-110-X schematic, which he proposed in 2002 (attached below). This circuit monitors the connected bus voltage and flashes a ...

I just uploaded a revised copy of the documentation for this project (now attached to the original post, above).

There was an error in the values specified for resistors R3 and R5. R3 should be 1. ...

Many aircraft builders have the skills and smarts to install an AOA Limiter system in their homebuilt aircraft. We need an electronics guru to design the circuit and program the microcontroller. Eri ...

As a conceptual diagram, it looks fine -- I see no errors in what you've done so far.

This post and the attached PDF document describe a heavily modified version of Bob's OVM-14 Mk III Overvoltage Protection Module. Instead of working as a crowbar, this design switches relay coils to ...

It seems to be a solution looking for a problem. The market is already awash in tried-and-tested fuse blocks that hold anywhere from single to dozens of fuses, making it easy to build buses that don' ...

I'm just sharing a project that I put together for myself, as I thought others might be able to get some use out of it. It's a board to give priority to the left trim switches (so the pilot can overr ...

There haven't been any updates on Bob's OVM-14 Mk III overvoltage protection module since Feb 2024 so I took a look at it to see what I could do. I found some minor things that might have been proble ...

Note: If the Matronics email system makes a mess of this message, please view it on the forum website. I included many links that are formatted for display on the forum and they may not translate pro ...

The subject of switching an airplane's antenna between a panel-mounted VHF comm radio and a handheld backup has been discussed here several times in the past, with no good solution (at least none that ...

I'll second the recommendation for the Ideal Industries StripMaster tool. You can buy one tool and multiple sets of dies to strip most common wire gauges.

Here are the part numbers and gauge range ...

That depends on what you're feeding through the diode (how much current it has to carry), and your tolerance for installation hassle. Generally speaking, you want something in a physically robust pac ...

Have you looked at Bob's newest electrical architecture, Z-101B?

http://www.aeroelectric.com/PPS/Adobe_Architecture_Pdfs/Z101B.pdf

This is his current state-of-the-art for an electrically depend ...

That MSD noise filter is almost certainly a Nippon ChemiCon U36D series capactor (like [url=https://www.digikey.com/short/52pftq70]this one) with a red shrink-wrap over it and the price wildly inflate ...

The AeroElectric-List landing page loaded OK, but when I tried to click through to this thread, I got the error again. One reload attempt brought it up this time.

Matt, I've been seeing a lot of "phpBB : Critical Error" messages lately when viewing the AeroElectric-List web interface. Repeated forced-reloads will sometimes cause it to load, but it's ...
