They said what some people are doing is using 3-conductor shielded wire and simply using the shield for ground. That's what I ended up doing since I had plenty of 3-c wire around. )_( Dan ----- Original Message ----- From: "Larry Bowen" Subject: RE: AeroElectric-List: 4-conductor shielded wire source > --> AeroElectric-List message posted by: "Larry Bowen" > > Doh!!

Thanks, John -- ________________________________ Message 9 _____________________________________ Time: 11:20:10 AM PST US From: N2321G@aol.com Subject: AeroElectric-List: Lamp Assy. Need A Source.. --> AeroElectric-List message posted by: N2321G@aol.com Im working on a project for an some industrial equipment and I need a lamp assembly as follows, (I seem to recall seeing these on GA airplanes) Panel indicator lamp, made in a fashion similar to a Whelan instrument post light, but the bulb is about 5/16" in diameter. The bulb has a smooth, flanged base, no threads. The bulb fits inside a 1/2" plastic "cube" that pushes into a flush mounted socket from the front of the panel. As I recall they were used in applications such as landing gear position indicator lights, where you could pull the bulb from one socket and stick it in the other to check if the gear had malfunctioned, or if the bulb was burned out. Does anyone know who makes these and what the source might be? ________________________________ Message 10 ____________________________________ Time: 11:24:44 AM PST US Subject: Re: AeroElectric-List: Threadlocker on nuts From: John Schroeder --> AeroElectric-List message posted by: John Schroeder Mark - One more choice: Sport Aviation, Feb 03, p115: Nylock has a self sealing patch to spray on the threads that will lock the bolts. Interesting concept. Let me know if you try it. John O ________________________________ Message 11 ____________________________________ Time: 12:01:55 PM PST US From: "Russ Werner" Subject: AeroElectric-List: Dynon encoder question --> AeroElectric-List message posted by: "Russ Werner" A friend at the hangar is wiring up his Dynon encoder functions to a KT76 Transponder. The encoder has a "strobe" line out. The old Ameriking encoder manual said to put this line to ground when using a KT76. Is this the case with any encoder and should the Dynon "strobe" line also be grounded? We're guessing so, but anyone with some knowledge here that can point us right would be appreciated.

Cunning. I've got some of the LED light bars on order. I've gone for the 30 x 7mm ones. Here's a further question for you or Bob, or anyone else using the LR3C alternator controller -- can I use your LED setup in place of the B&C-supplied bulb? It looks as though the output from the LR3C could fit right into the "+ve feed" part of your annunciator. Cheers.

Also the bolts supplied with the battery have an odd whitish cast making them appear to be a bit brittle whether they are or not.
