UENR4451-00 Sept 2014 Harness And Wire Electrical Schematic Symbols Symbols COOLANT TEMPERATURE SENSOR FUEL PRESSURE SENSOR INLET MANIFOLD AIR TEMPERATURE SENSOR WASTEGATE REGULATOR Pressure Symbol T Temperature Symbol Level Symbol Flow Symbol Circuit Breaker Symbol INLET MANIFOLD AIR PRESSURE SENSOR Symbols and Definitions 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.

ELECTRONIC CONTROL MODULE (ECM) SOLENIOD FOR HIGH PRESSURE FUEL PUMP 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. ATMOSPHERE PRESSURE SENSOR INTAKE PRESSURE FOR NRS 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. PRIMING/FUEL TRANSFER PUMP OUT PRESSURE SENSOR FOR NRS 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. 1204F -E44TA and 1204F-E44TTA Industrial Engines Electrical System CONTROL VALVE FOR NRS 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. T FUEL TEMPERATURE SENSOR 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.

PRIMARY SPEED/TIMING SENSOR TEMPERATURE SENSOR FOR NRS MT MU 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. OIL PRESSURE SENSOR 1 8 1 8 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 SIDE CONNECTOR SIDE Harness and Wire Symbols Wire, Cable, or Harness Assembly Identification: Includes Harness Identification Letters and Harness Connector Serialization Codes (see sample). Harness Identification Letter(s): (A, B, C, ..., AA, AB, AC, ...) Harness Connector Serialization Code: The "C" stands for "Connector" and the number indicates which connector in the harness (C1, C2, C3, ...).
