- a) Battery wires at the points of their contact with its terminals. The terminals must be clean and tightly tightened.
- b) Check the density of the electrolyte in the battery. If it is below the required value, recharge the battery.
- c) Check the external generator wires and their contacts. They must be in good technical condition.
- d) Check the technical condition of the drive belt and its tension (see chapter 1).
- d) Check the tightness of the generator mounting bolts.
- e) After turning on the engine, listen to the generator operation (the increased noise level can be caused by loosening of the drive belt pulley attachment, loose tightening of the generator mounting bolts, wear or contamination of bearings, as well as malfunctions in the diode rectifier unit or in the generator stator).
2. After turning off the engine, measure the voltage on the battery with a voltmeter. It should be approximately 12V.
3. Start the engine and measure the battery voltage again. It should be within 14-15 V.
