SERVICING THE ELECTRICAL SYSTEM

When servicing the electrical system, disconnect the negative cable from the terminal of the battery.

CAUTION

Before connecting or disconnecting the negative cable, be sure to turn off the ignition switch and the lighting switch (If this is not done, there is the possibility of the semiconduc- tor parts being damaged.)

Secure the wiring harnesses by using clamps so that there is no slack However, for any harness which passes to the engine or other vibrating parts of the vehicle, allow some slack within a range that does not allow the engine vibrations to cause the harness to come into contact with any of the surrounding parts, and then secure the harness by using a clamp.

If any section of a wiring harness interferes with the edge of a part, or a corner, wrap the section of the harness with tape or something similar in order to protect it from damage.

When installing any of the vehicle parts, be careful not to pinch

or damage any of the wiring harnesses.

90-2

If a burned-out fuse is to be replaced, be sure to use only a fuse

of the specified capacity If a fuse a capacity larger than that

specified is used, parts may be damaged and the danger of fire

also exists.

The sensors, relays, etc., must never be subjected to strong

shocks Do not allow them to fall and do not throw them when

handling.

The electronic parts used in the computer, relays, etc are

read-ily damaged by heat If there is a need for service operations that

may cause the temperature to exceed 80°C (176°F), remove the

electronic parts beforehand.

Loose connectors could troubles Make sure that the

connec-tors are connected securely.

If the connector is a sealed connector, insert the test probe in through the hole in the rubber cap for the electrical wires, being careful not to damage the insulation of the wires; continue to insert the test probe until it contacts the terminal.
