This document provides electrical component information for an excavator, including: - Component and connector location charts detailing where parts are located on schematics and the machine. - CID/MID/FMI codes for diagnosing faults in the engine/pump controller, engine controller, and tool controller modules. - Event codes and their meanings for the engine/pump and engine controllers. - Specifications for related manuals and an off-machine switch.

1. INTERACTIVE SCHEMATIC
The Bookmarks panel will allow you to
quickly navigate to points of interest.
Click on any text that is BLUE and underlined.
These are hyperlinks that can be used to navi-
gate the schematic and machine views.
When only one callout is showing on a machine view this
button will make all of the callouts visible. This button is
located in the top right corner of every machine view page.

Fuse (5 Amps)

T
Fuse: A component in an electrical circuit that will open the circuit if too much current flows through it.
Switch (Normally Open): A switch that will close at a specified point (temp, press, etc.). The circle indicates that the component has
screw terminals and a wire can be disconnected from it.
Switch (Normally Closed): A switch that will open at a specified point (temp, press, etc.). No circle indicates that the wire cannot be
disconnected from the component.
Ground (Wired): This indicates that the component is connected to a grounded wire. The grounded wire is fastened to the machine.
Ground (Case): This indicates that the component does not have a wire connected to ground. It is grounded by being fastened to the
machine.
Reed Switch: A switch whose contacts are controlled by a magnet. A magnet closes the contacts of a normally open reed switch; it
opens the contacts of a normally closed reed switch.
Sender: A component that is used with a temperature or pressure gauge. The sender measures the temperature or pressure. Its
resistance changes to give an indication to the gauge of the temperature or pressure.
Relay (Magnetic Switch): A relay is an electrical component that is activated by electricity. It has a coil that makes an electromagnet
when current flows through it. The electromagnet can open or close the switch part of the relay.
Solenoid: A solenoid is an electrical component that is activated by electricity. It has a coil that makes an electromagnet when current
flows through it. The electromagnet can open or close a valve or move a piece of metal that can do work.
Magnetic Latch Solenoid: A magnetic latch solenoid is an electrical component that is activated by electricity and held latched by a
permanent magnet. It has two coils (latch and unlatch) that make electromagnet when current flows through them. It also has an
internal switch that places the latch coil circuit open at the time the coil latches.
Harness identification code:
This example indicates wire group 325,
wire 135 in harness "AG".
L-C12

Wire, Cable, or Harness Assembly Identification:
Includes Harness Identification Letters and Harness
Connector Serialization Codes (see sample).
Harness Connector Serialization Code: The "C" stands for
"Connector" and the number indicates which connector in the
harness (C1, C2, C3, ...).

12. Components are shown installed on a fully operable machine with the key and engine off, transmission shifter
in neutral and with parking brake set.
Refer to the appropriate Service Manual for Troubleshooting, Specifications and Systems Operations.
Refer to the Parts Manual using a specific serial number prefix in SIS before ordering parts from this schematic.
