GENERAL DESCRIPTION:
- The emission and electrical control system operate ะพะฟ ะฐ twenty four volt power supply with negative ground polarity. Each wire in the vehicle is of ะฐ specific size and has an identifying colored insulation.
- These colors are indicated in wiring diagrams and will help in tracing circuits and making proper connections. Wire size is determined ะฌั load capacity and circuit length. Some wires are grouped together and taped. Such ะฐ grouping of wires is called ะฐ harness. The harness use ะฐ split corrugated tube to protect the wires from the elements. Each circuit consists of the following:
โข Power source – the battery and the alternator.
โข Wires – ะขะพ carry electrical current through the circuit.
โข Fuses – ะขะพ protect the circuit against current overload.
โข Relays – ะขะพ protect voltage drop between the battery and the circuit parts and to protect the switch points against burning.
โข Switches – ะขะพ open and close the circuit.
โข Load -Any device, such as ะฐ light or ะฐ motor, which converts the electrical current into useful work.
โข Ground – ะขะพ allow the current to flow back to the power source.
In this manual, such electrical device is classified ะฌั system. For major parts shown ะพะฟ the circuit based ะพะฟ the
circuit diagram for each system, inspection and removal and installation procedures are detailed.
