- Make sure the ignition is off before connecting the auxiliary battery.
- Make sure all electrical equipment is turned off (lights, heater, windshield wipers, etc.)
- Make sure the booster battery is the same voltage as yours.
- If another vehicle's battery is used as the auxiliary battery, the vehicles MUST NOT touch each other.
- Make sure the transmission is in position "neutral" (or "PARK" for automatic transmission).
1. Connect one end of the red transfer wire to the positive (+) terminal of a discharged battery.
2. Connect the other end of the red wire to the positive (+) auxiliary battery terminal
3. Connect one end of the black transfer wire to the negative (-) auxiliary battery terminal.
4. Attach the other end of the black wire to a bolt or motor bracket, away from the battery.
5. Make sure the portable wires do not touch the fan, drive belts, or other moving parts of the engine.
6. Start the engine with the auxiliary battery. When the engine starts to idle steadily, disconnect the portable wires in sequence. reverse connection.
Lighting from another car can, of course, temporarily solve your problem. However, it is important to find out the cause that led to the discharge of the battery. There may be three reasons for this:
1. The battery may have been discharged from numerous attempts to start the engine or because the external lights were not turned off.
2. Faulty battery charging system (the alternator drive belt is loose or broken, or the alternator wiring is faulty, or the alternator itself is faulty).
3. The battery itself is faulty (low electrolyte density or damaged plates).
