Battery — general information A discharged battery interferes with the normal operation of the vehicle. It does not allow the starter to turn in the normal way, nor to form a spark of sufficient strength to start the car engine. At the same time,...
Checking the electrolyte level in the battery The battery electrolyte consists of sulfuric acid diluted with distilled water. Part of the water may evaporate or decompose during the process of charging the battery into hydrogen and oxygen. The Renault 19 has a...
Checking the degree of discharge of the battery If the battery is very weak despite the correct electrolyte level, the degree of discharge should be checked. For control, you can use either a hydrometer or a voltmeter. The condition for a correct test result is that...
Removing and installing the battery First, remove the ground wire from the battery (minus), to exclude the possibility of a short circuit. 1. Carefully remove the engine hood seal from the front wall in the engine compartment. 2. Disassemble the plastic...
Charging the battery Even if the battery is not in use, it must be charged periodically. It tends to self-discharge over time. Therefore, the removed battery, just like the battery of a continuously operated machine, should be charged once...
Starting the engine with a dead battery Extreme care should be taken when towing, free-swinging or pushing a vehicle with a catalytic converter. If the engine does not start only because of a discharged battery, then this is not dangerous. Another thing is if...
Generator — design description Disassembled Valeo generator devices. The device of other generators is similar. 1 - V-belt pulley; 2 - fan; 3 - bearing cap on the drive side; 4 - stator winding; 5 - connecting bolt; 6 - rotor with slip rings; 7 -...
Voltage regulator — design description The faster the generator rotates, the higher the voltage rises and with it the electric current produced, as on a bicycle dynamo. Current consumers in a car cannot withstand such up and down voltage surges. Therefore, a...
Checking the voltage regulator Depending on engine variant (the figure shows the engine type «WITH») The V-belt must flex when pressed with a finger (shown by arrow) max. 6 mm (on a warm engine), otherwise it is necessary to adjust its tension by...
Checking the tension of the V-belt V-belt rotates on type motors «C» and «F» In addition to the generator, there is also a coolant pump. Therefore, special attention must be paid to the control of the V-belt tension. If the belt slips, this can be...
Checking the condition of the V-belt V-belt travel on motor type «WITH» (1), engine type «F» with servo steering (2), air conditioned (3) and additionally with servo steering and air conditioning (4). The arrow in each figure indicates where the belt...
Removing the generator 1. Disconnect the battery. 2. Disconnect the multi-pin connector. 3. Engine type «WITH»: loosen the tension bolt and the mounting bracket bolt. 4. Loosen the pivot screw. 5. Tilt the generator and remove the V-belt. 6....
Broken V-belt If during a trip the red warning lamp of the discharge suddenly lights up and you hear that something in the engine compartment hit the metal hard several times, then the V-belt is most likely broken. Be sure to stop...
Driving with a faulty alternator If the alternator or voltage regulator does not work, you can continue driving, as the battery is temporarily sufficient for this. Gasoline engine: during the day the battery current will last for some time, although...
Charging indicator lamp The control lamp on the instrument panel has two positive contacts, namely, on the one hand, from the terminal «1» generator (white wire) and, on the other hand, from the terminal «A2» ignition lock relay (yellow wire),...
Battery and alternator troubleshooting Battery and alternator Malfunction Her reason Trouble-shooting A. The red charging indicator lamp does not light up when the ignition is switched on. 1. Low battery. 2. The wire is broken, there is no contact at the...
Starter — design description Disassembled Paris-Rhone starter 1 - magnetic switch with starting plug; 2 - case of a magnetic switch with a winding; 3 - bearing cap on the drive side; 4 - drive mechanism of a small gear with a freewheel mechanism; 5...
Removal and repair of a starter Since a powerful diesel starter must develop a significant torque, it is additionally equipped, in the cover on the collector side, with a mount (3). The serviceability of the starter can only be checked in the removed...
Starter Troubleshooting Starter Not always our table will be able to help you troubleshoot the starter. But you always have the opportunity to start the Renault 19 engine (with manual transmission), by having someone push the vehicle or by...
