Hey Bob! 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!

Here's the finished project:

    Oh man . . . I don't recall the event at all.

    Were these pins with wire grips that extended

    out past connector body and would accept wire

    larger than 20AWG? I think I've see such

    pins in my travels but don't recall ever having

    some in hand . . . much less having shared

    them.

On that subject, I have one 18 gauge ground from my avionics stack that I  couldn't put into the ground bus.  I was going to run a separate wire to  the firewall forest of tabs.  Is there a better way?  Ditto on the  book and website.

  

 Thanks,

Perhaps they came from the 327 install kit?  Mine came with 4.

Well maybe I got them elsewhere then. 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.

   Cut 18AWG 6" short of reaching avionics ground bus.

   Butt splice or lap solder two 22AWG wires onto end

   of 18AWG. Then terminate the two smaller wires into the

   D-sub pins.

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

   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.

Thanks Bob & understood. I had run out of 20 at the time and it was a 

short run so 18 was called into duty. I split the load as described on 

the comm radios etc.

   Is the mag impulse coupled?

   What are you using for an ignition switch?
