There are times when a battery in a vehicle has such a low charge and in a emergency needs a jump start from another car to help it start.
This is done with jumper cables that hook to the battery on a car with a good battery to the dead battery.
Using jumper cables to jump start another vehicle is not difficult but can cause damage if done wrong.
Things to Remember When Jump Starting a Car or Truck.
…Never touch touch the clamps together as they are holding a charge once connected.
…The cables must be hooked up Positive-To-Positive and Negative-To-Negative.
…All jumper cables will have a RED cable that is hooked up to Positive and Black cable that is hooked up to Negative.
…Every Battery is also clearly marked with – and + symbols.
Step By Step How To Use Jumper Cables With Pictures
Make sure the negative clamps are not touching anything and free from touching the other clamp or grounding to the body of the car.
Connect the Red clamp to the Positive battery terminal on the bad battery.
Connect the other Red clamp to the good battery also marked Positive.
Connect the Negative clamp to the Negative battery terminal on the good battery.
Connect the Negative Black Clamp to the Negative battery terminal to the vehicle with the bad battery.
The jumper cable clamp should now be hooked up negative-to-negative, positive-to-positive from the good battery to the bad battery.
After the jumper cables are hooked up correctly start the vehicle with the good battery. Let it run for 5-10 minutes so it charges the dead battery.
Next start the vehicle with the bad battery.
Once the other vehicle starts remove the cables in reverse order Negative-Negative, Positive-Positive.
Any time electrical current is used there is a possibility of sparks or damage. This is because Positive and Negative can never touch.
Jump starting a car or truck is done all the time simply be sure to follow the correct steps and stay safe. If in doubt always call a professional.
It is also always a good idea to use a multi meter to test voltages when needed.
