6D1 – 6 ENGINE ELECTRICAL

JUMP STARTING PROCEDURE

1. Set the vehicle parking brake.

If the vehicle is equipped with an automatic
transmission, place the selector lever in the "PARK"
position.

If the vehicle is equipped with a manual transmission
place the shift lever in the "NEUTRAL" position.

Turn "OFF" the ignition.

Turn "OFF" all lights and any other accessory requiring
electrical power.

2. Look at the built-in hydrometer.

If the indication area of the built-in hydrometer is
completely clear, do not try to jump start.

3. Attach the other end of the same cable to the positive

terminal of the discharged battery.

Attach the end of one jumper cable to the positive
terminal of the booster battery.

Do not allow the vehicles to touch each other.

This will cause a ground connection, effectively
neutralizing the charging procedure.

Be sure that the booster battery has a 12 volt rating.

4. Attach one end of the remaining cable to the negative

terminal of the booster battery.

Attach the other end of the same cable to a solid
engine ground (such as the A/C compressor bracket
or the generator mounting bracket) of the vehicle with
the discharged battery.

This ground connection must be at least 450 mm (18
in) from the battery of the vehicle whose battery is
being charged.

WARNING:

Never attach the end of the jumper cable directly to
the negative terminal of the dead battery.

5. Start the engine of the vehicle with the good battery.

Make sure that all unnecessary electrical accessories
have been turned "OFF".

6. Start the engine of the vehicle with the dead battery.

7. To remove the jumper cables, follow the above

directions in the reverse order.

Be sure to first disconnect the negative cable from the
vehicle with the discharged battery.

REMOVAL AND INSTALLATION OF THE
BATTERY

REMOVAL

1. All switches should be in the "OFF" position.

2. Disconnect the battery ground cable.

3. Disconnect the battery positive cable.

4. Disconnect the battery 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.

INSTALLATION

To install the battery, follow the removal procedure in the
reverse order, noting the following points:

1. Make sure that the rod is hooked on the body side.

GENERAL DESCRIPTION

STARTING CIRCUIT

The cranking system consists of a battery, starter,
starter switch, starter relay, etc. and these main

components are connected as shown in Figure. For
details of the starting circuit.

STARTER

The starting system employs a magnetic type reduction
starter in which the motor shaft is also used as a pinion
shaft. When the starter switch is turned on, the contacts
of magnetic switch are closed, and the armature rotates.
At the same time, the plunger is attracted, and the pinion
is pushed forward by the shift lever to mesh with ring gear.
Then, the ring gear runs to start the engine. When the
engine starts and the starter switch is turned off, the
plunger returns, the pinion is disengaged from ring gear,
and the armature stops rotation. When the engine speed
is higher than the pinion, the pinion idles, so that the
armature is not driven.
