Removing and installing the battery Attention: If the battery is disconnected, then the record of malfunctions in the computer memory is erased and such systems that are often in operation, such as anti-blocking, radio, clocks, do not work. Before...
Checking the battery There are two possibilities for checking the battery. Depending on the test method, different instruments are needed. Electrolyte Density Check The density of the electrolyte along with the voltage give an indication of...
Battery charge Do not short-circuit the battery, i.e. plus (+) And (-) Batteries must not be interconnected. If a short circuit occurs, the battery will overheat and may crack. Do not expose the battery to naked flames. The...
Storage of the battery Batteries that have not been used for a long time self-discharge and can also become sulphated. If such batteries are charged using the accelerated method, they will not accept charging current or may appear charged....
Battery self-discharge In an unused car, the natural self-discharge of the battery is not dependent on the equipment of the car and is added by the consumption of electricity by some consumers. Therefore, when the vehicle is not in use, it is...
Generator — general description The COROLLA is equipped with an alternator. Depending on the model and equipment, generators can produce current from 40 to 70 A. The maximum current is indicated on the generator's branded bar. Attention: If additional...
Generator Safety Precautions When working with electrical equipment in the engine compartment, be sure to disconnect the ground wire (-) from the battery. Do not confuse the wires of the voltage regulator and the generator. Mark wires before...
Alternator voltage test Connect a voltmeter between the positive and negative poles of the battery Start the engine. When starting the engine, the voltage may drop to 8 V (at outside air temperature +20°С). Raise the engine speed to 2000 rpm....
Removal and installation of the generator Removing Disconnect ground cable (-) from the battery. Attention: As a result, the records in the memory of the on-board computer are erased. In particular, a fault record and a radio code. Before disconnecting the...
Checking and replacing the carbon brushes of the generator Generator brushes wear out rather slowly. On average, they wear out over 120,000 kilometers. However, it is recommended to replace them in advance. Alternators can be of different designs depending on the model of the...
Removal and installation of a starter To start an internal combustion engine, a small electric motor called a starter is needed. To start the engine, it must be spun up to at least 300 rpm. The starter consists of a drive part, a housing with poles and a...
Checking and replacing the magnetic starter Starter start circuit If there is a defect in the magnetic starter, the starter gear does not engage with the ring gear of the engine flywheel. This prevents the engine from starting. Examination Remove starter. Starter...
Starter Troubleshooting If the starter does not rotate, then first of all check if there is voltage at terminal 50 of the starter solenoid starter. The voltage should be at least 8 V. If there is voltage, check the starter circuit. Whether the...
