Introduction
If you’re having trouble starting your BMW, it may be due to a dead battery. Fortunately, you can jump start your BMW with a set of jumper cables and another vehicle. This article will provide a step-by-step guide on how to jump start your BMW.
Check the Battery
Before attempting to jump start the BMW, you need to make sure that the battery has enough charge to start the engine. To do this, use a multimeter to measure the voltage of the battery. If the voltage is below 12 volts, then the battery is dead and needs to be jumped.
Connect the Cables
Once you have confirmed that the battery is dead, you can begin connecting the jumper cables. First, attach one end of the red cable to the positive terminal of the dead battery. Then attach the other end of the red cable to the positive terminal of the working battery. Next, attach one end of the black cable to the negative terminal of the working battery, and attach the other end of the black cable to an unpainted metal surface on the BMW.
Start the Working Vehicle
With the cables connected, start the vehicle with the working battery and let it idle for at least five minutes. This will allow the power from the working battery to flow into the dead battery and help jumpstart the BMW.
Start the BMW
After the working vehicle has been idling for five minutes, try starting the BMW. If the engine does not start immediately, wait a few more minutes before trying again. If the engine still does not start, then the battery may be too far gone and you will need to take the car to a mechanic.
Disconnect the Cables
Once the BMW is running, disconnect the jumper cables in the reverse order that they were connected. Start by removing the black cable from the unpainted metal surface and then from the negative terminal of the working battery. Next, remove the red cable from the positive terminal of the working battery and then from the positive terminal of the dead battery.
Charge the Battery
After the BMW is started, drive it around for at least 15 minutes to help charge the battery. This will ensure that the battery has enough power to start the engine the next time you need to use it.
Visit a Mechanic
If the BMW will not start after following these steps, take it to a mechanic to have it checked out. The mechanic may be able to diagnose the problem and suggest a solution.
Conclusion
Jumping a BMW is a relatively simple process that can be done with a set of jumper cables and another vehicle. However, if the battery is too far gone, then you may need to take the car to a mechanic. Following the steps in this article will help you jump start your BMW quickly and safely.
