a) Check the density of the electrolyte of a fully charged battery at 20°C.
- Density - 1.25-1.27 kg/dm³
If the density is lower, charge the battery.
b) Check the electrolyte level in each cell of the battery and, if necessary, add distilled water.
2. Check that the battery terminals are securely connected and that there is no corrosion on them.
3. Check fuses and fuse links.
4. Check the drive belts of the attachments.
5. Inspect the wires going to the generator, check the reliability of their connection, the condition of the wiring, and the presence of extraneous noise coming from the generator when the engine is running.
6. Check the battery discharge indicator lamp circuit.
- a) Warm up the engine to operating temperature and turn it off.
- b) Turn off all auxiliary devices.
- c) Turn the ignition key to the "ON" position. The low battery indicator lamp should light.
- d) Start the engine. The lamp should go out. If the conditions are not met, check the test lamp circuit.
