- a) Check the condition and tension of the alternator drive belt (see Chapter Settings and ongoing maintenance). Replace if necessary;
- b) Check the generator mounting bolts for tightness;
- c) Check the condition of the generator wiring and electrical connections;
- d) If equipped, check the condition of the fuse link installed between the starter solenoid and the alternator, or the condition of the large main fuses in the engine compartment. If any knocked-out components are detected, identify and eliminate the cause of the overloads that occurred, then replace the defective components;
- e) Check the condition of all fuses included in the electrical circuit of the charging system. The location of fuses and fuse links may vary depending on the model and year of the vehicle (see Chapter On-board electrical equipment);
- f) Start the engine and evaluate the intensity of the background noise emitted by the generator;
- g) Check the density of the electrolyte in the battery cells, and recharge the battery if necessary;
- h) Make sure the battery is fully charged - one faulty cell can cause the battery to overcharge);
- i) Disconnect the negative cable from the battery first, then the positive cable.
Warning! If the car stereo system is equipped with a security code, before disconnecting the battery, make sure you have the correct combination to activate the audio system! Assess the condition of the battery wires where they are connected to the battery terminals. Check the reliability of the terminal clamps. After thoroughly cleaning the contact terminals, connect the battery.
2. Perform checks of the generator and voltage regulator operation (see Section Checking the correct functioning, removing and installing the generator).
