The circle indicates that the component has screw terminals and a wire can be disconnected from it.

No circle indicates that the wire cannot be disconnected from the component.

This indicates that the component has a wire connected to it that is connected to ground.

This indicates that the component does not have a wire connected to ground. It is grounded by being fastened to the machine.

Wire Gauge

Electrical Schematic Symbols And Definitions FUSE - A - A component in an electrical circuit that will open the circuit if too much current flows through it. REED SWITCH - A -  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.

Machinelocationsarerepeatedforcomponentslocatedclosetogether.  A= Locatedinoron therightconsole. B= Locatedinoron theleftconsole. T

SENDER - A -  A component that is used with a temperature or pressure gauge. The sender measures the temperature or pressure. Its r esistance changes to give an indication to the gauge of the temperature or pressure. RELAY (Magnetic Switch) - A -  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.

Machine Harness Connector And Component Locations

CIRCUIT BREAKER (C/B) -  A component in an electrical circuit that will openthe circuit if too much current flows through it. This does not destroy the circuit breaker and it can be reset to become part of the circuit again. SOLENOID - A - 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
