General information

On Patrol/Maverick cars the system of electric equipment working at tension of 12 V.Massa is applied becomes isolated on the minus plug of the battery. The battery is located in an impellent compartment.

In system of electric equipment of cars of the Patrol/Maverick series the generator of an alternating current of Hitachi firm is used. Advantage of the generator of an alternating current consists that the charging of the battery occurs already on single turns of the engine. At check of the generator remember that its rated target current can make both 50, and 60 And, depending on car model. The Hitachi generator established on model of 4.2 l of EFI (since 1992 вып.) has a target current 70 And and differs lack of the external fan.

The generator consists of motionless windings of a stator, a winding of a shaft (rotor), diode assembly of the rectifier and the built-in regulator of tension.

At course on windings of a rotor of an electric current (submitted through the brushes pressed to sliding contact rings, fixed on a shaft) in it (rotor) the magnetic field is induced. At rotor rotation in zvezdoobrazno located windings of a stator the three-phase alternating current is developed.

As the charging of the storage battery can be executed only by means of the power supply of a direct current, the generator is equipped with the diode rectifier fixed in a cover from contact rings of the generator.
Force of a target current is defined by the characteristic of the generator whereas management of target tension carries out the special built-in regulator. Control of the built-in regulator of tension is not represented possible.

For start of the engine one of two types of starters of Hitachi firm is used. Both starters treat on type to reduktorny with a food from tension 12 In, are equipped with the obgonny coupling (the coupling Bendiksa), disconnecting a starter from a gear wreath of a flywheel / a driving disk after engine start.

The electromagnetic traction relay is fixed on an arm of a forward cover of a starter. Plunzher of the traction relay via the lever of a drive influences assembly of a driving gear wheel with the obgonny coupling.

When giving food on windings of the traction relay its plunzher influences the lever of a drive which enters a driving gear wheel into gearing with a gear wreath of a flywheel / a driving disk, at the same time closing a chain of giving of a food from the battery on windings of excitement and an anchor of the electromotor of a starter.

After engine start the obgonny coupling of a driving gear wheel prevents damage of an anchor of the electromotor as a result of its compulsory rotation with high turns when the driver tarried with an ignition key otpuskaniye.
