When working on your pinball game it is sometimes necessary to disconnect a
wire (or wires) from an assembly.
There are two ways to help you remember which wire went where. One way is
to cut the wire back far enough from the assembly to leave a little
insulation. This insulation can be used to identify the wire that you just
removed. This way has the advantage of forcing you to remake the cut end.
This helps ensure that fresh wire gets used. Fresh wire will help you make
a good connection. As wiring in pinball games is famously tight. It can be
a better, and certainly easier, solution to simply unsolder the wire. In
this case it can be a good idea to mark the wire's location, on the assembly
or coil it came from, with black indelible ink. As there is usually not
very much space to write on, a color code can be used.
BK
Black
BR
Brown
RD
Red
OR
Orange
YL
Yellow
GN
Green
BL
Blue
VI
Violet
GR
Gray
WH
White
For single colored wires, the code is a two-letter abbreviation. (i.e.: The
location for a solid black wire is designated as BK.)
For two colored wires, the code is a combination of abbreviations. The
widest stripe is listed first. (i.e.: The location for a wire with a thick
black stripe and a thin brown stripe is designated as BK / BR.)
For multi-colored wires, the code is also a combination of abbreviations.
The widest stripe is listed first, then the thinner stripes are listed in
the order from the chart. (i.e.: The location for a wire with a thick black
stripe and a thin brown stripe and a thin red stripe is designated as BK /
BR / RD)
