The process of jumpstarting a car involves connecting the batteries of two cars together. However, it’s crucial to do it in the right order. Hooking up the cables in the wrong order could potentially damage the electrical components of the vehicle and even cause an explosion. So, which car do you hook battery cables to first?

The answer is simple: you always hook up the cables to the dead car first. The reason behind this is that connecting the cable to the dead battery first can create a spark, which can ignite the hydrogen gas that might’ve built up around the battery. This can result in a dangerous explosion. On the other hand, connecting the working battery first reduces the chances of sparks and explosion, making the process safer.

Before you begin jumpstarting your car, make sure that you have the right tools with you, including a set of jumper cables, a working car with a charged battery, and gloves. Once you have everything you need, you can follow these simple steps to jumpstart your car:

Step 1: Turn off both cars and open the hoods.

Step 2: Connect the red jumper cable to the positive terminal of the dead battery.

Step 3: Connect the other end of the red jumper cable to the positive terminal of the working battery.

Step 4: Connect the black jumper cable to the negative terminal of the working battery.

Step 5: Connect the other end of the black jumper cable to an unpainted metal surface (such as a bolt) on the dead car’s engine block, away from the battery.

Step 6: Start the working car and let it run for a few minutes.

Step 7: Try starting the dead car. If it doesn’t start, repeat the process and let the cars sit connected for a longer period.
