CONNECTOR

The connector pin shape determines whether the connector is
male or female.
The connector housing configuration does not determine
whether a connector is male or female.

The symbol illustrated in the figure is used as connector in the
circuit this section.

Connector is identified with a number.

The applicable terminal number is shown for each connector.

Connector terminal numbers are clearly shown.
Male side connector terminal numbers are in sequence from
upper right to lower left.
Female side connector terminal numbers are in sequence from
upper left to lower right.
NOTE:
For those connectors on which specific terminal numbers
on symbols are shown, the terminal numbers or symbols
are used in the circuit diagram, irrespective of the above
rule.

BATTERY

Inspection

1. Check the battery terminals 

1

 for corrosion.

2. Check the battery cables 

2

 for looseness.

3. Check the battery case 

3

 for cracks and other damage.

4. Check the battery electrolyte level.

If the electrolyte level is excessively low, the battery must be

replaced.

5. If  the  battery  has  a  built-in  hydrometer,  perform  the

following steps.

1) Carefully clean the battery upper surface.

2) Check the hydrometer.

The  hydrometer  design  will  vary  with  the  battery

manufacturer.

Refer to the illustration shown on the battery.

Battery Replacement

1. Disconnect the battery ground cable 

1

.

2. Disconnect the battery positive cable 

2

.

3. Remove the battery clamp

.

4. Remove the battery

Caution:
It is important that the battery ground cable be removed
first.
Removing the battery positive cable first can result in a
short circuit.

Jump Starting the Engine with a Booster Battery

The following description assumes that you are using a booster
battery mounted on a second vehicle.
The listed steps (with some minor modifications) are also
applicable if you are using a naked booster battery or special
battery charging equipment.

ELECTRICAL-BODY AND CHASSIS  8-19

Caution:
Never push or tow the vehicle in an attempt to start it.
Extensive damage to the emission system and other
vehicle parts will result.
(only catalytic converter vehicle)
Treat both the discharged battery and the booster battery
with great care when using jumper cables.
Carefully follow the procedure outlined below.
Always be aware of the dangers of sparking.
Failure to follow the following procedure can result in:
a.Serious personal injury, specially to your eyes.

b.Extensive  property  damage  from  a  battery  explosion,

battery acid discharge, or electrical file.

c.Extensive  damage  to  the  electronic  components  of

both vehicles.

Do not use a 24 volt booster battery.
Serious damage to the vehicle's electrical system and
electronic components will result.

Jump Starting Procedure

1. Set the parking brake on both vehicles.

2. If  one  or  both  vehicles  is  equipped  with  a  manual

transmission,  place  the  gear  shift  in  the  "NEUTRAL"

position.

3. Turn off the ignition on both vehicles.

4. Turn off all vehicle lights and accessories.

5. Check the  built-in  hydrometer  on  the  discharged  Battery  (If

so equipped).

If there is no hydrometer indication abandon the  jump  start

procedure.

6. Be sure that the two vehicles are not touching.

Attach  the  end  of  one  jumper  cable  to  the  booster  battery

positive terminal.

7. Attach  the  other  end  of  the  same  cable  to  the  discharged

battery positive terminal.

8. Once  again,  check  that  the  booster  battery  has  a  12  volt

rating.

9. Attach  one  end  of  the  remaining  booster  cable  to  the

booster battery negative terminal.

10.Attach the other end of the booster cable to a solid ground

(such  as  the  air  conditioner  compressor  mounting  bracket

or  the  alternator  mounting  bracket)  in  the  engine  room  of

the vehicle with the discharged battery.

Be sure that the ground connection is at least 500 mm (20

in) from the discharged battery.

Caution:
Do not attach the booster cable to the discharged battery
negative terminal.

11.Start the engine of the vehicle with the booster battery.

Check that all unnecessary electrical accessories are off.

12.Start the engine of the vehicle with the discharged battery.

13.Remove  the  jumper  cables  in  the  reverse  order  to  which

they were attached.

Caution:
Be absolutely sure to remove the negative jumper cable
from the vehicle with the discharged battery first.
