Rmag

We ran separate grounding straps from the mag to the airframe and the engine to the airframe. Made no difference. We just put a brand new mag on the right side. And for the first time when I did a mag check the right mag was dead silent only the left one had the noise. After I flew it for the first time the ticking noise came back even in the right side and stayed. Another very strange thing that happens is if I taxi to the middle of our airport the ticking goes away. But at both ends of the airport or in-flight the ticking is there. I did read a Beechtalk Post from a guy who had noises like this and he did not change his mag harness because it tested fine. After he changed it anyway his noise went away. My mag harness tests tests good but I'm thinking about changing this out now too. Is there coneses who makes the best spark plug wires? I have TCM/Bendix wires.

P1D put a featurette in his new video about my Mooney. I demonstrate many of the bells and whistles of the avionics suite. Jump ahead to 37:12 to watch.

I asked one of our upholsterers what machine would be cheap but still good. He said probably a Consew.

Well we swapped out the 2007 capacitor with a 2017 capacitor. Unlike the first time we replaced the capacitor, this time it had no effect at all. He's thinking you may be on to something with the coil.

Happy to report that Norm @Little Dipper is scheduled with SureFlight his new panel upgrade. He's getting some nice equipment installed, but not to steal his thunder, I'll let him share all the exciting details.

Nice looking plane, looks like the paint is in good shape too.

I went with streamlining the panel and running it all through the GTN 750. I don't think the transponder is a big deal. You tap the screen and hit 4 big giant numbers and enter. If you already have a nice ADSB transponder, no need to change, but I needed one so I went remote. The audio panel interface on the other hand is awesome. It is very easy to graphically see your intercoms, who hears what bluetooth music, etc. It's just a really nice graphical user interface. Where the GMA-35c GTN 750 pairing really shines is controlling the GTN 750 with Telligence voice control. I'd say the absolute best use of it is automatically tuning frequencies without having to look them up. You can command with your voice: Tune Nearest (or Destination) Tower, CTAF, Unicom, Ground, Clearance, Departure, Approach, etc. Tune Nearest (or Destination) Weather, AWOS, ASOS, ATIS, etc Second from that you can verbally select or monitor COM1 or 2 I also use it to quickly toggle between Map, Traffic, Flight Timers pages, VCALC page, etc. You Zoom in or Zoom out verbally. So it shortcuts navigating the GTN 750. Instead of say 3 button presses to access something I can just verbally command it to go where I want. It can also tell you things verbally. I can ask it time to descend and it gives me a verbal time, or I can get a verbal bearing and distance or eta to a waypoint or destination. You don't have to look at a thing or press anything. The EDM placement I put right above the throttle. I like it there. I tend to scan it more than the RAD to make sure all my gauges are in the green.

My noise went from non existent to back again without moving anything in between.

Would this be noticeable on a mag test? This is where I am going next.

No No evidence of arcing between the points when the mag was apart.

No shower of sparks. It's an impulse coupling. Bendix S-1200 mags. I completely disconnected the P leads and ran it to take out that wiring. Mag harness was tested with a high tension lead tester and ohm meter. They are not shorted out or degraded. The noise can still be heard in a unwired handheld radio too. i'll look again at the bonding strap and the mag housing... The thing that's killing me is that the noise went away when we initially did the capacitor.

The saga continues. I'm starting to get frustrated. Changing the magneto capacitors made the noise go away. But it slowly came back over my next two flights and now it's as bad as it originally was. The fact that the noise went away and then came back makes me wonder if the 2007 "new" capacitor degraded while on the shelf for 10 years. Maybe it worked and then failed? Anyone know of a shop that has test rigs to energize and leak test bendix mag capacitors near SE PA?

Never mind...

Watch the interview with DeWitte. First thing they talk about.

Technically 7 days to full cure.

Here is what we did with him:

I saw that that was a problem when I loaded my first ILS approach. I'm pretty sure that I had the ILS frequency loaded the next few times I flew. Hopefully the weather will cooperate this weekend and I'll be able to do more testing. Sent from my Nexus 7 using Tapatalk HD I know you have the Aspens, but this is the instructions for the G500 how the GPS has to be setup. Might be the same for the Aspens? Step 1 is load an ILS approach, step 2 is have the ILS frequency active (not standby). 2.7.4 Auto-Slewing The G500/G600 system is designed to interface with GPS navigator units and also manage up to four different CDI course pointers (GPS1, NAV1, GPS2, NAV2) independently. The G500/G600 will automatically slew the NAV course pointer to the correct nal approach course when a ILS, LOC, LOC BC, LDA or SDF approach is active in the GPS navigator and the appropriate frequency is in the active window in the navigator. The G500/G600 will Auto-Slew the HSI course pointer for an ILS, LOC, LOC BC, LDA, or SDF approach when the steps below are completed in the following order: The desired approach is selected and activated in the navigator (this can be veried by the approach waypoints appearing on the GDU 620 MFD Nav Map Page or FPL Page). The appropriate frequency is the active frequency in the navigator. The CDI selection on the GDU 620 is changed to NAV course pointer for the active navigator.

I should have had you knock on wood. While the right condenser replacement removed the chopping at low RPM, I flew yesterday and at high RPM the chopping noise was there just as bad. So we replaced the condenser in the left mag today. On a ground run up to 2400 RPM today, the chopping was gone. The two removed condensers were dated 2000. So they were 17 years old. The new ones we put in were dated 2007 and 2016.

As mentioned earlier, I had my A636D converted to to the A636 specification. I just so happened to be looking at my data plate today while my right magneto was apart. My plate is stamped 25° timing. Is this because of my engine conversion? Is 25° timing considered a desirable thing vs 20°?

The A&P that fixed mine had a capacitor in stock brand new never used, but the date was 2007. Even when you order a new part, no gauranty how new the date will be.

Less than 15 since overhaul.

Its kind of ironic that it was the "Rmag" that was the problem.

Well, It was the right magneto condenser/capacitor. We replaced it and no more noise. I was incorrect in what I wrote above; I thought the noise could be isolated by running on the L mag switch. Apparently such is not the case. My A&P surmised that even though the R mag is grounded, it is still spinning so the bad capacitor could still send out RF interference.
