Essential Tools for Jump Starting a Car

Step-by-Step Guide: How to Jump Start a Car

Now that you understand the basics and have the necessary tools, let’s walk through the process of jump starting your car:

Step 1: Position the Vehicles

Drive the car that is functioning close to the one without power and ensure they are near each other so that the jumper cables can easily reach from one to another. 

Always see to it that you have placed both performances in park (or neutral in case of manual transmissions off the ignition and set the parking brakes as well.

Step 2: Locate the Batteries

Open both cars’ hoods and identify the batteries. Usually, the battery is right at the front center under the hood on all automobiles.

Step 3: Identify the Battery Terminals

Find the terminals in each battery of positive and negative polarity. The positive terminal will be positively signed (+) and always in red while the negative terminal will have a minus sign (-), which is usually black.

Step 4: Connect the Jumper Cables

This is the most critical step in the jump start process. Pay close attention to the order of connections:

1. Connect one red clamp to the positive terminal of the dead battery.

2. Connect the other red clamp to the positive terminal of the good battery.

3. Connect one black clamp to the negative terminal of the good battery.

4. Connect the other black clamp to an unpainted metal surface in the engine bay of the car with the dead battery. This serves as a ground and helps prevent sparking.

*Remember: Red to dead, red to the donor, black to the donor, black to ground.

Step 5: Start the Working Vehicle

Turn on the working car’s engine and let it run, this should transfer some charge to the flat battery.

Step 6: Attempt to Start the Dead Car

Before starting the car, ensure you have properly connected the wires, as they are easily misplaced. Never let the jumper cords come into contact with anything that moves under the bonnet. 

Once everything’s clear, fire up the car with a good battery and let it run for a few minutes. This gives your dead battery a chance to recharge. Now, try starting your car. If it won’t start, give the good car another 10-15 minutes to idle and try again. Still no luck? Unfortunately, a jumpstart might not be the answer. Call a reliable car repair Dubai to help you with the jump start. 

You can also go for car recovery Dubai services to have your car towed and repaired simultaneously.

Step 7: Disconnect the Cables

Once the dead car is running, carefully disconnect the jumper cables in the reverse order you connected them:

1. Remove the black clamp from the ground on the jumped car.

2. Remove the black clamp from the negative terminal of the good battery.

3. Remove the red clamp from the positive terminal of the good battery.

4. Remove the red clamp from the positive terminal of the jumped car.
