The Electrical System Schematic, Parts Manual, and Operation and Maintenance Manual for the machine that is being serviced should be used to locate electrical components and connectors.

The following information is a guide to reading the tables on the back of the Electrical System Schematic.

The "Component Location" table uses white circles to mark the locations in the profile of the machine and in the area views. Alphabetical letters in the "Machine Location" column indicate a general area of the machine. Refer to the corresponding footnote at the end of the table for a description of the location.

The "Harness Connector Location" table uses white circles to mark the locations in the general view and in the area views. Alphabetical letters in the "Machine Location" column indicate a general area of the machine. Refer to the corresponding footnote at the end of the table for a description of the location.
