My light wires (second photo) look different (something under the shrink tubing) than the one in this thread. I've got a PM into Dean but trying to get this done this weekend while the temps are in the 70s :). Anyone know if these are the "new" lights and if they should be grounded differently?

Mine are the same and I suspect they're just ferrite beads designed to filter out interference and that wiring should be identical.

But Dean's the authority. :-)

Just read this thread and corrected my strobe wiring per the photo.

Now I have dead silence on the intercom !

I have NS90s and a suntail. Using a handheld com around the strobes to check for noise was a great idea from one of the previous threads.

I wired per the AeroLED diagram grounding shield at both ends and had lots of strobe noise. After rewire per photo, leaving both ends of shield grounded, absolutely quiet.

AeroLED should pitch that diagram and just show the above photo on their website.

THANKS !

I had noise problems with my AeroLeds at first,but after wiring them according to the diagram - one ground from the light, one ground from the three wire shield, and one ground from the light chassis all grounded locally on the same screw, everything was completely silent (per AeroLed wiring diagram). Then I installed a new G3X panel and the magnetometer mounted in the tail are didn't like the strobe EMI emanating in the tail area with the strobes on. I had to run a dedicated ground from the Suntail AeroLed on the tail unit to the firewall ground to prevent magnetic interference in my Garmin magnetometer. Now I have a noise in my headset from the tail strobe. It's not very loud and is drowned out with engine power above about 1500 RPM, but it's not totally silent anymore (I use A20 Bose headsets).

I have read of this condition a couple times. But I want to note that I have the G3X, with magnetometer in the tail and aeroleds with Suntail. All my aeroleds are wired per the diagram and grounded locally, including the suntail. I have no magnetometer interference with this setup.

Has this change been made for units purchased within the last year or is grounding to be done as pictured still?

Ground location for tail light
 

Where in the tail did you place your local ground for aft position/strobe liget and possibly trim servo?

Did you bring the ground to the fuselage? Turtle Deck? One of the aft bulkheads? Horizontal Stabilizer?

Thanks

pics please
 

Does anyone have pictures of a successful installation of the tail and wing tip wiring with airframe connections and just for wishful thinking wiring around an archer wingtip nav antenna?

Here is a photo of how I managed the tail light case ground on my -7A. Made from "O" material. This ground goes into the tail and is grounded with the internal and shielding ground wires on the aft bulkhead.

The shield ground is accomplished by stripping a small section off the shielded wire within the tail and a solder splice with a wire inserted. It then ties to the internal ground in a single connector. I have photos of the inside but they are on my camera at the hangar.
