I just ordered an ELT tester that tests the ELT's for their yearly re-certification. The owner of the company I bought the tester from told me not to be surprised if the ACK units like your fail the test. He claims many or most ACK 406 ELT's fail.

Please provide an update when you resolve the problem. I'm seeing a similar issue with my ELT install. A check of the pins shows correct wiring/soldering.

ACK got back to me with this

Plug the remote directly into the ELT cable if it works it is the cable or audio alert unit.

That's all they wrote. I guess it's worth trying, I could even plug it into the first cord coming out of the ELT and bypass the extension cord they supply. I'll test this tonight and post my results.

Hi Claude,
My new ELT tester will hopefully show up by the end of the week. If you are bored and looking for an excuse to fly somewhere, you could fly up to EE6 and we to hook yours up to the tester and see if it passes or fails? I always enjoy seeing RV's here!!

I cannot recall if I tested it back then and don't have my log books nearby. Anyways, back to this test. I pressed the test/reset button and nothing happens at all. I tried again after checking the main unit behind my baggage wall. Still nothing. I checked all of the phone cord connections from the ELT to the audio module and then to the remote. I'm going to pick up a new battery for the remote and try that, but does anyone have any ideas on what could make the simple test fail? I can try turning the ELT on from the main unit while my baggage wall is down, but haven't done that yet.

Pierre,
Strangely, I did the exact same thing within the past 48 hrs.
I also changed both batteries (front and in the rear by the unit), re-did the telephone wire and it worked.

Interesting proposition Phil. What does that hook up to? And how's the grass at EE6? I haven't done a grass field landing before and my first will need to be in great shape. Of course the rain is going to have to let up.
I'm planning a big trip to the east coast, leaving here on the 29th weather permitting. I would like a shorter cross country warmup, especially after my annual.

i had the same issues with my remote/switch until i looked closely at the 'phone' cable supplied with the unit. It is not a standard phone cable! Standard phone cables have the wires on the opposite ends of the cords reversed - ie. Brown/Red/Green/Yellow at one end and Yellow/Green/Red/Brown at the other. The cable supplied with the unit has the same pinout colours at either end and are not crossed. Once I made proper cables the same way everything worked just fine. You can also purchase a crossover coupling if you use a standard phone cable to reverse the pins back before they connect with the unit. i ended up doing this with the cable from the audio unit back to the ELT in the rear. Needed a coupling anyway back here to connect the extension with the unit so i just had to use a crossover unit instead of a standard coupling. If you do use a standard phone cable just make sure it has wires connected to all four pins as some cables are intended for single line jacks and only have the middle two pins wired.

And all of this sort of begs the question...*telephone cord*? (Or telephone-cord-like stuff)? In an aircraft? What the...?
Yeah, I have an Ameriking, uses the same stuff, but I just shake my head at this...to me, it's up there with using RG-54 TV cable for coax. Yeah, it'll work, but it just ain't right.

I had the same problem about a year ago. The audio alert unit was bad. I went around it as they suggested to you to isolate the problem. They quickly sent a new alert unit which solved it.
