That avionics ground bus you sell worked great on my project. Included in the kit were some long D-sub female pins. I used some to double up small wires and to attach a few 18 awg wires with. Can you tell me the PN# please? I need a few more. BTW, the panel & electrical is now about done, I used your ideas, book & web page a great deal on this project so thanks for the help!

I did put all the pins from the install kits into the same container, I bet they came from Garmin. They are about 1/4" longer and will accept a 18awg wire, why longer I have no idea.

Butt splice or lap solder two 22AWG wires onto end of 18AWG. Then terminate the two smaller wires into the D-sub pins. Bob . . . ________________________________ Message 8 _____________________________________ Time: 02:34:09 PM PST US Subject: Re: AeroElectric-List: Avionics ground bus From: Franz Fux Hi Bob, I would like to ask you a question regarding the wiring of the starter in my plane. It has the left mag and an electronic ignition. I fly an RV7 wired according to Diagram #11 and the addition of #25 (I believe) for the electronic ignition on the top plugs. The way it is wired I need to have the mag on and the electronic ignition off in order for the starter to engage. I would like to change over to either start on both or the electronic ignition only for better starting. Could you let me know how I would go about accomplishing that task Thanks Franz Fux RV7A 450h ________________________________ Message 9 _____________________________________ Time: 02:34:24 PM PST US From: "Robert L.

Because the wire grip for 18AWG won't go into the d-sub connector housing. So they use a longer pin to effect the crimp just outside the housing. I'd prefer to spread the loads over two pins as putting a too-big wire into one pin. See previous post.

I split the load as described on the comm radios etc. Tim ________________________________ Message 12 ____________________________________ Time: 04:24:06 PM PST US From: "Robert L.
