ELECTRICAL SUPPLY SYSTEM

The electric power circuit supplies electric current to each electric component. It consists of a battery, battery relay, starter switch, circuit breaker, fusible link and fuse box.

The negative terminal of the battery is grounded to the vehicle body.

Even when the starter switch (5) is in the "OFF" position, electric currento is supplied toothe following components through battery

(1) fusible link (3) fuse box (6).

1.Terminal "1" of DC-DC converter (for memory backup of stereo)

2.Terminal "B" of starter switch

3.Hour meter

4.Engine controller

5.Fuel feeder pump switch

6.Terminal "6" of wiper motor

7.Terminal "13" of wiper controller

8.Terminal "CN6-11" of instrument panel

9.Terminal "CN9-6" of air conditioner panel

10.Cabin light

When the starter switch (5) is in the "ONo or START" positions,o

the currento flows from the battery (1) fusibleo link (3) fuse box (6) "B" terminalo of starter switch (5) "BR" terminal of starter switch (5) "BR" terminal of battery relay (2) which activates the coil of the battery relay and the electric supply system is energized.

When the battery relay's contacts are connected, all electric devices can be operated.

While the engine is not running, the electric power for all electric devices are supplied by the battery. Once the engine is started the power is supplied from the alternator (7).

ENGINE STARTING CIRCUIT

Start Operation

When the starter switch is turned to the "START" position, the "S" and "E" terminals of the starter controller (7) are connected. At this time the contacts in the startero relay (8) areoclosed by the ocurrent flow from the battery (1) fusibleo link (3) fuse box (6)

"B" terminalo of starter switch (5) "C" terminal of startero switch (5) "30" terminal of starter relay (12) -o"87a" terminal "C" terminal of starter relay (8) - "D"o terminal "S" terminal of starter controller (7) - "E" terminal ground.

When the contact point "B" and "PP" of starter relay (8) are connected, the pinion gear of the starter (9) is pushed forward and makes contact with the ring gear of the flywheel and the internal contacts of theo starter are connected. The currentoflows from the battery (1) "A" terminal of the batteryo relay (2) "B" terminal of the battery relay (2, Figure 3) "B" terminal of the starter (9). The starter motor is rotated and the engine is started.

If the instrument panel has the password function activated , input number should match the set number, otherwise the start circuit closes and the engine does not start.

NOTE: If the security system is "LOCKED," a four-digit password will be required to start the engine. If the system is "UNLOCKED," no password will be required and this display screen will not appear.

In the event the securityo system is locked,o current flowsofrom battery (1) fusible link (3) ofuse box

(6) "B" terminal of startero switch (5) "ACC" terminal of startero switch (5) "86" terminal of startero relay (12) "85" terminal of startero relay (12)

"CN1-15" terminal of e-EPOS (13) ground. This current flow causes the coil in starter relay (12) to be activated, opening contacts at "87a" terminal. This prevents starter relay (8) from functioning.

After Start

Once the engine has been started, the belt driven alternator (10) generates a current.

The output generated by the alternator (10) is a square wave pulse voltage through the "P" terminal and the frequency of the pulse voltage is proportional to the rotation of the alternator.

The starter controller (7) monitors the frequency of the output current. Once the frequency is equivalent to 500 rpm, it is sensed and the connection between "S" and "E" terminals and the connection between "B" and "PP" terminals are opened. As a result the rotation of the starter (9) is stopped. Once the engine is running, the starter (9) will not operate even if the starter switch (5) is moved to the start position, preventing possible damage to the starter.

ENGINE PREHEATING SYSTEM

An air heater (8) is installed in the intake manifold of the engine. When the starter switcho (5) is turned "ON,"o the currentoflows from the battery (1) fusibleo link (3) fuse box (6) "B" oterminal of starter switch (5) "BR" terminalof starter switch (5)

"1-39" terminal of engine controller (12), causing ocurrent to flow though "1-16" terminal of engineo controller (12) "C and D" terminals ofopreheat relay (7) "1-04" terminals of engine controller (12) ground.

This current flow causes the coil in preheat relay (7) to be activated, closing contacts.

When the contacts of the preheat relay (7) are closed, the heating coils of the air heatingo device (8) are heatedo by current flowingo from the batteryo (1) battery relay (2) preheat relay

(7) air heater (8) ground.

The duration of the heating cycle depends on the temperature of engine coolant. The preheat indicator light in the instrument panel (9) will turn "ON" during preheating cycle.

The preheat relay (7) is controlled by the engine controller (12) and operates only at temperatures of 10°C (50°F) and below.

The longer the preheating period, the lower the temperature of coolant is.

ENGINE STOP

When starter switch (5) is turned "ON" the engine controller (8) is activated. The engine controller monitors and controls the engine including the injector solenoid (9). It controls the fuel deliver rate and the injection timing for each cylinder.

NOTE: There is an individual injector solenoid (9) for each of the six cylinders. Only one soleniod is shown in Figure 7.

When starter switch (5) is turned "OFF," the engine controller stops suppling power to the injector solenoid (9). This stops fuel from being injexted into the engine cylinder, thus stopping the engine.

In the event that the engine can be shut down using the starter switch (5), an emergency stop switch (10) is provided to shut down engine. To activate the emergancy stop switch, move it to the "I" (EMERGENCY STOP) position.

The emergency stop switch (10) is in its "O" (OFF) position during normal operation. The switch must be moved and held in the "I" (EMERGENCY STOP) position until the engine stops. When released it will automatically move back to the "O" (OFF) position.

CHARGING SYSTEM

When the starter switch (5) is turned to the "ON" position, an initial excited current flows to the field coil of the alternator (7) through the battery relay (2) and circuit breaker (4). When the engine is started from this condition the alternator (7) starts charging. Theo current flows fromo the "B(B+)" terminalo of alternator (7) circuit breaker (4) battery relay (2) battery

(1).

The alternator also supplies electric current to other electrical components. When the alternator (7) startsoto operate,oa current flows from the "R(I)" terminal of alternator diode (8) battery relay (2) coil securing a path for the charging current to the battery (1). Thus preventing the possibility of a high voltage build up and possible damage to the electric system.
