ENGINE ELECTRIC SYSTEM
Vehicle accessories are left on overnight.
Slow average driving speeds are used for short periods.
The vehicle’s electrical load is more than the alternator output, particularly with the
addition of aftermarket equipment.
Defects in the charging system, such as electrical shorts, a slipping alternator belt, a faulty
alternator, or a faulty voltage regulator.
Battery abuse, including failure to keep the battery cable terminals clean and tight or a
loose battery holddown clamp.
Mechanical problems in the electrical system, such as shorted or pinched wires. -

3) CHARGING SYSTEM
Alternators use a new type of regulator that incorpo-rates a diode trio. A Delta stator, a rectifier
bridge, and a rotor with slip rings and brushes are electrically similar to earlier alternators.
A
conventional pulley and fan are used.
There is no test hole.
4) CHARGING TIME REQUIRED
The time required to charge a battery will vary depending upon the following factors:
Size of Battery
- A Completely discharged large heavy-duty battery required more than twice the recharging
time as a completely discharged small passenger car battery.
Temperature
<00540047004700680047009300960095008e008c00990047009b00900094008c0047009e00900093009300470089008c00470095008c008c008b008c008b0047009b00960047008a008f00880099008e008c00470088009500a0004700890088009b009b00
8c009900a000470088009b004700540058005f00b6006a0047>(0°F) than at 27°C
(80°F).
When a fast charger is connected to a cold battery, the current accepted by the battery will
be very low at first. The battery will accept a higher current rate as the battery warms.
Charger Capacity
- A charger which can supply only 5 amperes will require a much longer charging period
than a charger that can supply 30 amperes or more.
State-of-Charge
- A completely discharged battery requires more than twice as much charge as a onehalf
charged battery. Because the electrolyte is nearly pure water and a poor conductor in a
completely discharged battery, the current accepted by the battery is very low at first. Later,
as the charging current causes the electrolyte acid content to
increase, the charging current will likewise increase. ▶

5) CHARGING A COMPLETELY DISCHARGED BATTERY
(OFF THE VEHICLE)
Unless this procedure is properly followed, a perfectly good battery may be needlessly
replaced. The following procedure should be used to recharge a completely discharged battery:
Measure the voltage at the battery terminals with an accurate voltmeter. If the reading is
below 10 volts, the charge current will be very low, and it could take some time before the
battery accepts the current in excess of a few milliamperes. Refer to “Charging Time
Required” in this section, which focuses on the factors affecting both the charging
time required.
Such low current may not be detectable on ammeters available in the field. 1.
Set the battery charger on the high setting. 2.
Some chargers feature polarity protection circuitry, which prevents charger unless the charger
leads are correctly connected to the battery terminals. A completely discharged battery may
not have enough voltage to activate this circuitry, even though the leads are connected
properly, making it appear that the battery will not accept charging current.
Therefore, follow the specific charger manufacturer’s instruction for by passing or
overriding the circuitry so that the charger will turn on and charge a low-voltage battery.
Continue to charge the battery until the charge current is measurable. Battery chargers vary
in the amount of voltage and current provided. The time required for the battery to accept a
measurable charger current at various voltages may be as follows: 3.
If the charge current is not measurable at the end of the above charging times, the battery
should be replaced.
If the charge current is measurable during the charging time, the battery is good, and
charging should be completed in the normal manner. -
-
It is important to remember that a completely discharged battery must be recharged for a
sufficient number of ampere hours (AH) to restore the battery to a usable state.
If the charge current is still not measurable after using the charging time calculated by the
above method, the battery should be replaced. -

6) JUMP STARTING PROCEDURE
Position the vehicle with the charged battery so that the jumper cables will reach from the
charged battery to the battery that requires charging.
Turn off the ignition, all the lights, and all the electrical loads in both vehicles.
Leave the hazard flasher on if jump starting where there may be other traffic and any other
lights needed for the work area.
Apply the parking brake firmly in both vehicles. 1.
2.
3.
4.
In order to avoid damaging the vehicle make sure the cables are not on or near pulleys, fans,
or
other parts that will move when the engine starts.
Shift an automatic transmission to PARK. 5.
In order to avoid injury, do not use cables that have loose or missing insulation.
Clamp one end of the first jumper cable to the positive terminal on the booster battery. Make
sure it does not touch any other metal parts.
Clamp the other end of the same cable to the positive terminal on the discharged battery.
Never connect the other end to the negative terminal of the discharged battery. 6.
7.
Do not attach the cable directly to the neg-ative terminal of the discharged battery. Doing so
could cause sparks and possible battery explosion.
Clamp one end of the second cable to the negative terminal of the booster battery.
Make the final connection to a solid engine ground, such as the engine lift bracket at least
450 millimeters (18 inches) from the discharged battery.
Start the engine of the vehicle with the good battery.
Run the engine at a moderate speed for several minutes.
Then start the engine of the vehicle with the discharged battery.
Remove the jumper cables by reversing the above sequence exactly, removing the
negative cable from the vehicle with the discharged battery first. While removing each
clamp, take care that it does not touch any other metal while the other end remains
attached. 8.

7) ALTERNATOR
Alternators are equipped with internal regulators. Unlike three-wire alternators, the alternator
may be used with only two connections: battery positive and an “D+” terminal to the
charge indicator lamp.
As with other charging systems, the charge indicator lamp lights when the ignition switch is
turned to RUN, and goes out when the engine is running. If the charge idicator is on with the
engine running, a charging system defect is indicated. This indicator light will glow at full
brilliance for several kinds of defects as well as when the system voltage is too high or too low.
The regulator voltage setting varies with temperature and limits the system voltage by
controlling rotor field current. Achieve correct average field current for proper system voltage
control by varying the on-off time. At high speeds, the on-time may be 10 percent and the off-
time 90 percent. At low speeds, with high electrical loads, the on-time may be 90 percent and
the off-time 10 percent.

POWER STEERING SYSTEM
RODIUS 2005.07

4. OVERVIEW
The power steering system consists of pump, oil reservoir, rack and pinion gear. The power
steering pump is a vane type and delivers hydraulic pressure to operate the power steering
system. The pressure relief valve in pump controls the discharging pressure.
The rotary valve in rack and pinion gear directs the oil from the power steering pump to one
side of rack piston.
The integrated rack piston converts the hydraulic pressure to linear movement.
The operating force of rack moves the wheels through tie rod, tie rod end and steering knuckle.
Even though the hydraulic pressure cannot be generated, a driver can steer the vehicle without
power assist but it needs very high steering force.
In this case, the operating force of steering wheel is conveyed to pinion, and the movement o
f
pinion moves the rack through pinion gear combined to rack gear.

POWER STEERING SYSTEM
3. POWER STEERING PUMP
The vane type pump that is connected to engine by belt is used for the power steering system.
This pump generates and controls a proper hydraulic pressure and flows by using the flow
control valve and pressure relief valve.
The flow control valve regulates the excessive amount of discharging oil. When the steering
wheel is stationary or the oil circuit is blocked, the pressure relief valve returns the ove
r
pressurized oil to the oil reservoir.
4. OIL RESERVOIR
The oil reservoir sends the oil to the power steering pump and receives the oil from the power
steering gear.
The oil level in the reservoir depends on the steering wheel positions. therefore, measure the oil
level when the steering wheel is positioned at straight ahead direction (neutral).
