HITCH GP-CUSHION 8X4981 - Caterpillar

A semiconductor device that will let current flow (conduct) in one direction only. A diode will conduct only when its anode is more positive (+) than its cathode by a specific amount.ELECTRICALTo have a relation to electricity.ELECTRICAL COMPONENTA component that is part of an electrical circuit.ELECTRICAL SYSTEMThe organization of all of the electrical components in some application that work together.ELECTRICITYThe characteristic of basic particles to have a positive or negative charge. The flow of electricity is current; the pressure or potential of electricity is voltage.ELECTROMAGNETA magnet made by the flow of current through a coil of wire.ELECTRONICTo have a relation to electricity, especially to circuits that have semiconductor components.FLASHWhen a lamp or LED turns ON and OFF at a regular rate.FORWARD BIASAn application of voltage in the direction that a semiconductor component will normally conduct.FUSE A component in an electrical circuit that will break (open) the circuit (make a not complete circuit) if too much current goes through it. A fuse is destroyed when it breaks a circuit.GROUNDTo be connected to the negative (-) side of a battery; can be connected with a wire and/or the metal of the vehicle. When the negative (-) side of the battery is connected to the vehicle, the metal of the vehicle is at ground potential.External Ground A component has an external ground when it has a wire fastened to a connection on the component that is connected to ground [to the negative (-) side of the battery or to the metal of the vehicle].Internal Ground A component has an internal ground when it is connected to ground because it is in contact with the metal of the vehicle. It does not have a wire that is fastened to a connection on the component and to ground.GROUNDED WIREWire that is in contact with the metal of the vehicle (ground). It can be because of a loss of insulation from the wire, or because the end of the wire is connected to the vehicle.HARNESSAn assembly made of a few, or many wires that is held together by a cover.INDICATORA lamp or LED that gives an indication of some vehicle condition, when it turns on or flashes.INSULATORSomething that has the characteristics of insulation. A material that has a very large resistance so that it will not let current flow throuh it (conduct).MAGNETA material that has lines of force around it that attracts (pulls) iron to it.MAGNETIC FIELDThe lines of force around a magnet or an electromagnet that causes iron to be pulled to it. MAGNETIC SWITCHA relay.NEGATIVEThe (-) side of a battery. The direction to which current flows. When the negative side of the battery is connected to the metal of the vehicle, the vehicle is negative, or ground.NORMAL CONDITIONWords used with a switch or relay. Their
