Hi All,
What type of connectors do I use when connecting to things such as the fuel pump and the fuel level senders.
Regards
Mike

Use the most secure connectors (ring type that bolt on).

Sorry, let me rephrase that, do I use a plug (if yes then what type) or do I use a terminal block or something else.
Thanks
Mike

Hello Mike, If you are making in line wire to wire connections my preference
is Molex AVIKRIMP, fully insulated, crimp on, male and female, quick
disconnects. Here is a data sheet on the male version:
http://www.molex.com/molex/products/datasheet.jsp?part=active/0190010001_QUICK_DISCONNECTS.xml&channel=Products&Lang=en-US
and here is a data sheet on the female version:
http://www.mouser.com/ProductDetail/Molex/19003-0040/?qs=zb2cXSD1GSE7hqjLVfW3MA%3d%3d
These terminals will come in the standard red, yellow, and blue colors
indicating the wire gage size that the terminal is intended to be used with.
They will also come in different metal tab widths. The most popular width
tab seems to be 0.250 inches. The female version is also used on a wire when
the electrical device or fixture is equipped with male push on, or FASTON
tabs.
Avikrimp terminals also come in ring versions for use in connecting wire to
a threaded stud on the electrical fixture. Here is a sample data sheet:
http://www.molex.com/molex/products/datasheet.jsp?part=active/0190730168_RING_AND_SPADE_TER.xml&part=active/0640011500_APPLICATION_TOOLIN.xml&channel=Products&Lang=en-US
These come in a variety of wire gage sizes (red, yellow, and blue) and rings
sizes to fit various stud sizes. Shop around. These are not cheap. Here is
one potential source:
http://www.terminaltown.com/index.htm
You may go a bit cheaper by using insulated (but not fully insulated)
terminals and covering them with heat shrink tubing, but unconnecting is
then more difficult.
Here is one tool for crimping these terminals:

Here is another one:

Hello Again Mike, If you are connecting to a device that has just a few
wires, say 3 or less, then connecting each wire individually is probably the
easiest. See my earlier post on terminals to use when connecting wires
individually.
If you are going to be connection many wires, and particularly if these
wires will be disconnected and reconnected frequently during the aircraft's
operation, then some kind of multi wire connector may be suitable.
When it comes to multi wire connectors many factors can influence the
selection of the type of connector, such as: cost, amount of amperage per
wire going through the connector, size of wire, frequency of disconnecting
and reconnecting, accessibility of the connector, reliability of the
connection, and probably some more factors that don't come to mind right
now.
Some commonly used multi wire connector types are: D sub miniature, plastic
block (such as AMP Mate n Lock, or Molex), and circular types, commonly
called "Cannon Plugs".
There is no "one size fits all" solution. Why don't you give us a few of the
specific connection problems that you are trying to solve and we can come up
with some suggestions.

PS: Terminal blocks for connecting to individual items spread througout the
electrical system are probably one of the least favorite ways of making
these connections.

Hi Mike,
I used Amp CPC connectors, series 1. My philosophy was that everything should have a quick disconnect connector on it. Landing lights, fuel senders, trim servos, etc. I also have a 16 pin connector at each wing root and six 16 pin connectors between the instrument panel and fuselage so I can remove the panel easily which I've had to do a lot more times then I ever thought I would. I also put bellcrank bearings on the panel so it can fold down which has made things much, much easier.
www.mouser.com has them. It's a bit hard to find them on the website, but if you click on the catalog tab and look on page 1288 they are there.
I attached a picture of what I did.
For me the electrical stuff seemed overwhelming initailly, but it ended up being the most fun part of the project.
I got pretty much everything electrical from mouser or http://www.bandc.biz/
The military surplus places have great deals on wire sometimes. Don't buy anything electrical from aircraft spruce. They don't even spool the wire.
Cheers,
Scott

Hi All,
What type of connectors do I use when connecting to things such as the fuel pump and the fuel level senders.
Regards
Mike
