GENERAL DESCRIPTION:
- The emission and electrical control system operate оп а twenty four volt power supply with negative ground polarity. Each wire in the vehicle is of а 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 Ьу load capacity and circuit length. Some wires are grouped together and taped. Such а grouping of wires is called а harness. The harness use а split corrugated tube to protect the wires from the elements. Each circuit consists of the following:
• Power source – the battery and the alternator.
• Wires – То carry electrical current through the circuit.
• Fuses – То protect the circuit against current overload.
• Relays – То protect voltage drop between the battery and the circuit parts and to protect the switch points against burning.
• Switches – То open and close the circuit.
• Load -Any device, such as а light or а motor, which converts the electrical current into useful work.
• Ground – То allow the current to flow back to the power source.
In this manual, such electrical device is classified Ьу system. For major parts shown оп the circuit based оп the
circuit diagram for each system, inspection and removal and installation procedures are detailed.
