Modern vehicles with electronic management systems should not be jump started without “protected” jump starter leads and it is necessary to refer to the owner’s handbook for jump starting procedures for such vehicles.
Batteries generate explosive gasses during vehicle operation and when being charged. Flames, sparks, burning cigarettes or other ignition sources must be kept away at all times.
Always shield eyes when working near batteries:
When charging batteries, work in a well ventilated area – never in a closed room. Always turn the battery charger or ignition off before disconnecting a battery.
Vehicle Jump Starting, procedure is as follows and should be followed carefully:
- Check batteries are the same voltage.
- Turn off all electronic loads, check vehicles are not touching and are in park or neutral.
- Check that vehicles have the same terminal earthed. If not, refer to manufacturers instructions.
- Inspect both batteries before connecting booster cables.
- Do not jump start a damaged battery.
- Refer to the vehicle owners’ manual for other specific information
- Carry out following steps in sequence:
1. On negative grounded system, Connect positive (+) booster cable to positive (+) terminal of discharged battery
2. Then Connect the other end of the positive (+) cable to the positive (+) terminal of the assisting battery
3. Connect one end of the negative (-) cable to the negative (-) terminal of assisting battery.
4. MAKE THE FINAL CONNECTION OF THE NEGATIVE (-) CABLE TO THE ENGINE BLOCK OR CAR FRAME OF THE STALLED VEHICLE, AWAY FROM BATTERY.
5. Make sure cables are away from fan blades and other moving vehicle parts.
6. Start the engine of the assisting car.
7. Attempt to start the engine of the vehicle with the discharged battery.
If vehicle does not start within 30 seconds, call an auto electrician or road service organisation.
After starting, remove cables in reverse order, starting with the one connected to the engine block or car frame.
