- a) Making repeated unsuccessful attempts to start the engine, or leaving the lights on for a long time with the engine off;
- b) Malfunction of the charging system (the generator drive belt is loose or broken, the connecting electrical wiring is damaged, or the generator itself is faulty).
- c) Malfunction of the battery itself (the electrolyte level has dropped, or the battery"s service life has expired).
When performing engine starting from an external power source, attention should be paid to observing some special precautions:
- a) Before connecting the auxiliary battery, make sure the ignition is off;
- b) Make sure that all electrical consumers (lighting and heating devices, windshield wipers, etc.) are also switched off;
- c) Wear protective gloves and glasses;
- d) Make sure that the auxiliary battery has the same output voltage as the one installed in your vehicle;
- e) If a battery installed in another vehicle is used as an auxiliary power source, ensure that the vehicles NEVER come into contact with each other;
- f) Make sure that the transmission is in neutral (manual transmission) or in position "P" (automatic transmission);
- g) Remove the ventilation caps from the battery to be serviced and cover the openings with a rag.

Connect one end of the red wire from the special kit to the positive terminal of the dead battery (see accompanying illustration). Connect the other end of the red wire to the positive terminal of the auxiliary battery.
Connect one end of the black cable from the kit to the negative terminal of the booster battery. Connect the other end of the black cable to a reliable ground point on the block of the engine being started (bolt or bracket), as far away from the battery as possible.
Make sure that the connecting wires do not come into contact with moving components in the engine compartments of both vehicles (fan impeller, drive belts, etc.).
Perform the standard engine starting procedure. Leave the engine idling. Turn on the headlights, rear window defroster, and heater fan, then disconnect the wires in the reverse order of how they were connected. When the procedure is complete, turn off unnecessary electrical consumers.
Note: Auxiliary power consumers are switched on to prevent voltage surges when the electrical wiring is disconnected.
