What terminal should the red jumper cable be connected to?
One is marked positive (+), the other negative (-). There are also positive and negative cables in the jumper cable set. The red one is positive (+), the black one is negative (-). Never connect the red cable to the negative battery terminal or a vehicle with a dead battery.
Where does the red jumper cable go?
The positive (red) cable should be attached to the positive terminals on each battery. The negative (black) cable should have one end attached to the negative terminal of the dead battery, and one end grounded.
What jumper cables go on first?
Attach the red jumper cables first. Start by clamping one red cable to the positive side of the battery that won’t start. Then attach the other red clamp to the positive side of the working battery. Next, clamp one black cable to the negative side of the working battery.
Does red or black go first when jumping a car?
Step 3: Identify the jumper cables: Red is for the positive charge, black for the negative. The thicker the cables, the better the jump. Don’t let the clamps of the opposing cables touch, or you may get a shock. Step 4: Take the red jumper cable and affix one clamp to the positive post of the dead car battery.
How long do you leave jumper cables connected?
Wait two minutes as you turn on the engine. Wait an additional two minutes after turning on the dead one. You can let the car run for two more minutes if you remove the cable in the reverse order you put it on.
How do you use jumper cables in Australia?
One end of the red jump lead should be connected to the flat battery’s positive terminal. The lead must not touch any vehicle metal. Attach the red lead’s other end to the boosting battery’s positive terminal. Take the black lead and connect one end to the boosting battery’s negative terminal.
Why do you ground the negative jumper cable?
The reason for connecting the negative cable to ground rather than to the negative terminal of the dead battery is to minimize the chances of a spark near the battery, where there may be potentially explosive gasses. Disconnect the cables and attempt to start the car with the bad battery.
What happens if you connect both negative jumper cables?
Hooking the jumper cables up backwards can create disastrous results. Possible outcomes include irreparable damage to the battery, fried electronics, and even serious personal injury. You might cause personal injury and/or damage to your car if you accidentally hook your jumper cables up wrong.
What happens if you connect the negative terminal first?
Connect positive first, negative having less potential won’t arc. The higher the voltage, the greater the chance of arcing and fusion. On a car if negative first and you are touching any metal part of car, when attaching positive there is possibility of arcing through you. Your body becomes part of the circuit.
Where to connect jumper cables?
Connect the Cables Begin by parking the vehicle with the good battery next to the car with the dead battery. Open the hoods of both cars and locate their batteries.

How do you connect a jumper cable to a dead battery?
Connect one of the black clamps to the negative (-) post of the good battery. Make sure the clamp is firmly connected. But instead of connecting the other end of the cable to the negative post of the dead battery, clamp it to a bare, metal surface on the engine of the dead car — like a bolt or a screw.
