    8A-4 ELECTRICAL-BODY AND CHASSIS

    GENERAL INFORMATION

    The body and chassis electrical system operates on a twelve volt power supply with negative ground polarity.
    The main harness consists of the engine harness, the instrument harness, the body harness, and the chassis
    harness.
    The harnesses use a split corrugated tube to protect the wires from the elements.
    Wire size is determined by current flow, circuit length, and voltage drop.
    All wires have color-coded insulation.
    Wire color-codes are shown in the circuit diagrams.
    This makes it easier to trace circuits and to make the proper connections.

    Each circuit consists of the following:

    5. Power source – The battery and the alternator

    5. Wires – To carry electrical current through the circuit

    5. Fuses – To protect the circuit against current overload

    5. Relays – To protect voltage drop between the battery and the circuit parts and to protect the switch points

    against burning

    5. Switches – To open and close the circuit

    5. Load – Any device, such as a light or motor, which converts the electrical current into useful work

    5. Ground – To allow the current to flow back to the power source

    NOTES FOR WORKING ON ELECTRICAL ITEMS

    Battery


    BATTERY CABLE

    Disconnecting the Battery Cable
    5. All switches should be “OFF” position.

    5. Disconnect the battery ground cable.

    5. Disconnect the battery positive cable.

    CAUTION:
    It is important that the battery ground cable be
    disconnected first.
    Disconnecting the battery positive cable first can result in
    a short circuit.












    Connecting the Battery Cable

    Follow the disconnecting procedure in the reverse order to
    connect the battery cables.
    CAUTION:
    Clean the battery terminal and apply light coat of grease to
    prevent terminal corrosion.


    CONNECTOR HANDLING

    Disconnecting the Connectors

    Some connectors have a tang lock to hold the connectors
    together during vehicle operation.
    Some tang locks are released by pulling them towards you

    1

    .

    Other tang locks are released by pressing them forward

    2

    .

    Determine which type of tang lock is on the connector being
    handled.


    Firmly grasp both sides (male and female) of the connector.
    Release the tang lock and carefully pull the two halves of the
    connector apart.
    Never pull on the wires to separate the connectors.
    This will result in wire breakage.
