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