The following is an explanation of terms and symbols
which are standard on Crown wiring diagrams.
Wiring Color Codes
Wires are limited to the colors shown in the chart be-
low. The color of the wire is based on the function of the
circuit in which it is used. Each wire is assigned a three
or four digit number. The first one or two numbers iden-
tify the color of the lead. The last two numerals number
the lead from one thru ninety-nine. Exceptions to this
can be component leads supplied by vendors. Each
wire is identified by a number on a wiring pictorial (refer
to section DIA).
Power Cables
Except WP trucks, power cables are designated using
one of the following abbreviations, followed by a dash
number.
An example of such a cable is PC # 1/0 - 10. The part
number for this cable is 084572-010.
