SECTION 6
WIRING DIAGRAMS
&
SCHEMATICS
ATTENTION SERVICER: For the first eight years of production, the wiring of 500 Series units
differed between the Madison and Phoenix facilities. This means that the wiring diagrams for
Madison and Phoenix also differed for the first eight years.
The wiring diagrams in this section are in the best possible Serial Number order, with the dia-
grams applying to Madison production units preceding those applying to Phoenix production
units. In some instances it is necessary to skip over pages to reach the continuation of the next
set of applicable serial numbers. This is indicated in a "NOTE" at the top of the appropriate
pages.
Before referencing any wiring diagrams in this section, you must know where the unit in question
was produced, this is indicated by a "M" (for Madison production) or a "P" (for Phoenix produc-
tion) at the beginning of the serial number on the serial tag.
