Just another approach.  

  

 We got 400 pairs of numbered heat shrink,  300 pairs of 3/32" and 100 pairs of 1/4" - Each label being 3/4" long, www.merithian.com - total cost was  about US$60.  

  

 Every wire / cable then has one label on  each end and a spreadsheet for look up for wire size / termination / routing /  function.

  

 So far has worked really well.

My 2 cents on wire numbering.  

   

My schematics are identified via two letters – FP for Flaps, PW for electrical power etc.  

Each wire on a particular schematic has its number, starting with 1 and going up  

Each wire belongs to a circuit identified by two letters, independent of the schematic, starting with AA, then AB, then AC etc.  

All this of course is contained in spread sheets via an export of the schematic wire identification labels.  

   

Each wire is therefore numbered as follows: SSNNCC where SS is the schematic, NN is the number and CC is the circuit. Hence when I look at a wire, for example FP34EA I know that it is wire #34 on the Flaps schematic and it belongs to circuit EA (power to the flap motor – excel spreadsheet).  

   

The reason for labelling the circuit in is that two wires MUST be on the same circuit when they join. Hence if I find two wires on a connector with labels FP34EA and PW45EA respectively then I know it is OK. But if the circuits do not match – they are not connected correctly. An EA wire should connect to another EA wire and nothing else. This is the key to render connecting things together pretty well fool proof as far as connector blocks are concerned.  

   

That’s it – I found it makes connecting things and tracing them quite easy – saves a lot of time and reduces the risk of a ‘Smoke gets in your eyes..’. Later on, when time comes for maintenance or trouble shooting, this numbering system should be a great help. Of course, if the schematic is wrong…

I used Microsoft Word to print all my labels using

a 6 pitch font.  Rather than a numbering scheme,

I used full text describing the wire.  Examples below:



(3) DYNON D10A GROUND

(1) DYNON D10A TO ESSENTIAL BUSS 12V +

(2) DYNON D10A  KEEP  ALIVE  POWER



With this format I know the pin number, the purpose, and the destination.  I 

cut the label, lay it on the wire, slide a piece

of heat shrink over the two, and heat briefly.  For hard-to-

read locations I use two labels (one reversed.)  It's a bit

time consuming but works well...
