Provides DC current for the auto's various electrical circuits.\n\nCAPACITOR (Condenser)\nA small holding unit for temporary storage of electrical voltage Capacitors with a ground connection are frequently called Condensers.\n\nCIGARETTE LIGHTER\nAn electric resistance heating element.\n\nCIRCUIT BREAKER\nBasically a reusable fuse, a circuit breaker will heat and open if too much current flows through it. Some units automatically reset when cool, others must be manually reset.\n\nDIODE\nA semiconductor which allows current flow in only one direction.\n\nDIODE, ZENER\nA diode which allows current flow in one direction but blocks reverse flow only up to a specific voltage. Above that potential, it passes the excess voltage. This acts as a simple voltage regulator.\n\nDISTRIBUTOR, IIA\nChannels high-voltage current from the ignition coil to the individual spark plugs.\n\nFUSE\nA thin metal strip which burns through when too much current flows through it, thereby stopping current flow and protecting a circuit from damage.\n\nFUSIBLE LINK\nA heavy-gauge wire placed in high amperage circuits which burns through on overloads, thereby protecting the circuit.\n\nGROUND\nThe point at which wiring attaches to the chassis, thereby providing a return path for an electrical circuit; without a ground, current cannot flow.\n\nHEADLIGHTS\nCurrent flow causes a headlight filament to heat up and emit light. A headlight may have either a single (1) filament or a double (2) filament.\n\n1. SINGLE FILAMENT\n\n2. DOUBLE FILAMENT\n\nHORN\nAn electric device which sounds a loud audible signal.\n\nIGNITION COIL\nConverts low-voltage DC current into high-voltage ignition current for firing the spark plugs.\n\nLIGHT\nCurrent flow through a filament causes the filament to heat up and emit light.\n\nLED (LIGHT EMITTING DIODE)\nUpon current flow, these diodes emit light without producing the heat of a comparable light. Used in instrument displays.\n\nMETER, ANALOG\nCurrent flow activates a magnetic coil which causes a needle to move, thereby providing a relative display against a background calibration.\n\nMETER, DIGITAL\nCurrent flow activates one or many LED's, LCD's, or flourescent displays, which provide a relative or digital display.\n\nFUEL\n\nMOTOR\nA power unit which converts electrical energy into mechanical energy, especially rotary motion.\n\nM","image":"https://tsrm.sasquatchvc.com/images/mk3-ewd/GLOS/GLOS_001.png","url":"https://tsrm.sasquatchvc.com/mk3/ewd/GLOS/1","prev":null,"next":{"page":2,"url":"https://tsrm.sasquatchvc.com/mk3/ewd/GLOS/2","api":"https://tsrm.sasquatchvc.com/api/pages/mk3/ewd/GLOS/2"},"section_url":"https://tsrm.sasquatchvc.com/mk3/ewd/GLOS","section_api_pages":["https://tsrm.sasquatchvc.com/api/pages/mk3/ewd/GLOS/1","https://tsrm.sasquatchvc.com/api/pages/mk3/ewd/GLOS/2"],"note":"OCR transcript of a scanned Toyota factory manual page; verify critical values (torque specs, part numbers) against the image."}
