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 indicatesthat 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 ofa 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: 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.

NOTE B: FOR SPEEDOMETERS OR TACHOMETERS WITH A SINGLE SIGNAL INPUT TERMINAL, EITHER ONE OF THE TWO SIGNAL OUTPUT LINES FROM THE ECM CAN BE USED. LEAVE THE REMAINING LINE DISCONNECTED, DO NOT CONNECT TO GROUND.NOTE C: "SINGLE" WINDING MAGNETIC PICKUP SENSOR RECOMMENDED.NOTE D: THESE CONNECTIONS ARE UNSWITCHED, DIRECT CONNECTION TO THE BATTERY IS NOT REQUIRED.NOTE E: THE ECM SPEEDOMETER AND TACHOMETER OUTPUT SIGNAL LINE VOLTAGES ARE ZERO-CROSSING SQUARE WAVES. THE SPEEDOMETER SIGNALS AT J1-37 AND J1-36 ARE COMPLEMENTS OF EACH OTHER. THE TACHOMETER SIGNALS AT J1-38 AND J1-39 ARE COMPLEMENTS OF EACH OTHER. MAXIMUM SIGNAL AMPLITUDE OF J1-36, J1-37, J1-38, AND J1-39 IS +/- 10 VOLTS. AMPLITUDE WILL BE +/- 5 VOLTS OR GREATER IF LOAD CURRENT IS LESS THAN 4mA.NOTE F: IF AN ELECTRONIC SIGNAL IS PROVIDED IN PLACE OF A PASSIVE MAGNETIC SENSOR, CONNECT THE ELECTRONIC SIGNAL INPUT TO THE +SIGNAL PIN, THE -SIGNAL PIN SHOULD NOT BE CONNECTED OR GROUNDED WITH ELECTRONIC SIGNAL INPUTS.NOTE G: WIRE NUMBER 386 IS FOR AIR SHUTOFF AND IS SPECIFIC TO HARNESS 243-2321. WIRE NUMBERS G856 AND G857 ARE FOR THE TIMING CALIBRATION(TC) PROBE AND ARE SPECIFIC TO HARNESSES 243-2321 AND 248-2433.NOTE H: ONLY APPLIES TO ENGINES WITH AIR SHUTOFF OPTION.NOTE L: SENSOR RETURN CONNECTION FOR INPUTS #1, #8, AND #11 MAY BE MADE TO EITHER J1-5 OR J1-18. J1-18 IS FOR BODY BUILDER/AFTERMARKET INSTALLATIONS.NOTE X: USE KIT 156-7106 WHEN REPLACING CONNECTOR 153-9693.
