This has caused me a lot of grief. I am not sure who did this as we
    had several people employed at the time it was done. At least 4
    crimp connection came undone as the wrong tool was used to crimp the
    terminals.

    A real rats nest.

    No advanced planning, schematic  or 3D drawings. (If you are
    building an airplane a 3D drawing program is a HUGE HELP!!!)

    Make sure you space things far enough apart so a socket wrench can
    be used to tighten or loose the nuts holding the CB's and switches.

    I am still trying to clean it up.


    Switches and circuit breakers come with either Phillips or straight
    slot screws.

    Absolutely and with out a doubt the worst possible solution. You
    need three hands with tiny fingers to assemble the wiring to the
    switch or CB. One hand to hold the wires and another to insert and
    hold the screw in place and a third to use the screw driver to
    tighten the screw.

    Either Allen screws or small stand offs work 10 to 100 times better.
     The  hex driver or the Allen wrench can do the last two jobs If you
    tape the allen or hex screw to the end of the driver.

    The schematic is still a work in progress.

    Hey Paul, If you need some real screws, we have lots of Philips head
    stuff up hear in Canada! Yes 3D, EAA has free Solidworks with
    membership!

    Steve Carlisle

    You are joking of course. I hate them. Nothing but trouble my entire
    life.

    Paul Lamar

    Steve, you must be referring to Robertson. Americans don't like them
    because invented by a Canuk. Paul, use Vaseline. Dip the Phillips
    screw driver in a jar to get a bit on the end. Works to hold bolts
    or nuts in sockets also.

    Vaseline is not strong enough. Allen head or better yet 6-32 stand
    off's.

   Paul,

   True Phillips or slotted screws are fine, but you need to assemble into a harness terminating in a multipin connector, and remove/replace as one unit rather than trying to wrestle individual breakers and wires in the cockpit. The good cheap lightweight connectors these days are AMP CPC types, some up to 35 amps continuous.

   David Josephson

   They are not fine when you are upside down working in a confined space.
   Have you ever wired or tried to wire an instrument panel installed in an aircraft?

   Unless you want to rip it all out and start over AMP CPC types are irrelevant.
   The Motec and the M&W do not use AMP CPC types.

   Each aviation electric or electronic device device has its own set or type of connectors.
   There is no standardization.

   You have to work with them. If they use Phillips or slotted screws it is easy to
   change to hex or stand offs. These are much easier to use than Phillips or slotted screws.

   Paul Lamar

Robertson work about as well as Allen. Then there is Torx just to confuse the issue more.

Dale Davies

Got any pictures of a Robertson?
