Instead of the starter getting your engine moving, you are getting the engine to move by letting go of the clutch while it is moving. Thanks! Yes No Not Helpful 8 Helpful 20 Do I need to run the car for 15 minutes after a jump start? wikiHow Contributor You should run your vehicle for 15 to 30 minutes after a jump start to allow your alternator to charge the battery.

The voltages of both batteries must match, or you risk doing serious damage to both batteries. The amperage does not have to match, however; in fact, it’s preferable to have the “good” battery be of higher amperage than the “bad” battery. Thanks!

What can I do? wikiHow Contributor You can try to connect your jumper cable to the positive cable running from the battery to the starter.

The Other Way: Start the car with the fully charged battery and let is sit idling for roughly five to ten minutes to charge the dead battery. Attempt to start the car with the dead battery without shutting off the fully charged car. If the car with the dead battery refuses to start, let it sit for a few more minutes. If the car with the dead battery still will not start, very carefully readjust the red (+) positive cable to the terminal in hopes of getting a better connection. Reattempt to jumpstart the car. If the vehicle starts, remove the cables in the reverse order they were put on, being careful not to let them touch.

How to Jumpstart a CarIt’s never too late to learn. Most Popular Charles Williams – Flickr CC By Timothy Dahl Jan 26, 2017 When your car doesn’t start, you most likely have a dead battery and the fastest way to get back on the road is a quick jumpstart. This simple trick takes less than five minutes and only requires a set of jumper cables and another vehicle. If you’ve never got around to learning the particulars or the ins-and-outs of doing it safely, we’ve got you covered.Jumper CablesAny pair of jumper cables is better than not having any at all. But if you are buying new cables, look for ones that are 4 to 6 gauge in size and at least 20 feet in length. Beefier cables and heavy duty clamps will be more durable and provide a better connection. It’s not always possible to place vehicles right next to each other, so having longer cables will ensure the batteries can reach each other.Advertisement – Continue Reading BelowThis jumper cable set from Cartman costs less than $20 and comes in a handy bag that can easily fit in your trunk or under a seat.Making the ConnectionWhen handling jumper cables, keep the red and black clamps from touching, ensuring your cables aren’t mishandled when setting them up. Also try to have one person at each end to make the connection and prevent the clamps from touching. If the clamps do touch when they are hot, you could cause a short in either vehicle and create some dangerous sparks. Most PopularStart by making sure the running vehicle with a good battery is parked next to the vehicle that is dead. Open the hood of each vehicle and identify where the battery is located. Many times there is a plastic hood covering the battery or the battery posts. You’ll need to remove this hood to access the posts. It’s best to have the proper tools to do this before you get into a situation like this, so take the time to get familiar with how your battery is setup.Once you have access to the battery posts, determine which one is positive (+) and negative (-). The positive post may have a red cable attached, but it’s best to look for a plus or minus sign to determine its polarity.Brush away any dirt or gunk from the posts because you’ll need to create as clean and solid connection as you can. First connect one end of the red clamp to the positive post on the dead battery. Then connect the matching end of the red clamp to the positive post on the functioning battery.Next, connect the black or negative clamp to the negative terminal on the good battery. Instead of connecting the remaining negative clamp to the dead battery, find an unpainted engine bolt or piece of the vehicle’s frame and secure your clamp to that. This will ensure a safer jump situation.Start Your EnginesStart the functioning vehicle first, then try to start the dead vehicle. If the interior lights come on and you hear the engine turn over but it won’t start, then you may have another issue. If you hear a clicking sound when you try to start the vehicle, you might have a bad starter.Use a multimeter to test your battery voltage. It varies with vehicle types, but it should read slightly more than 12 volts when the vehicle is turned off. If your battery is in good shape, then it’s time to troubleshoot other issues.If your vehicle fires up and your jump was successful, leave it running while you carefully disconnect the cables, making sure the clamps don’t touch. Keep your vehicle running until you’ve reached your destination, which will give it ample time to recharge so you aren’t stuck again with a drained battery.More from Popular Mechanics:

Read your owner's manual before attempting a jumpstart. Newer cars often have jumpstart lugs where the cables need to be attached, instead of directly to the battery terminals. In addition, some manufacturers do not allow jumpstarting the vehicle at all, and doing so may void the warranty. In some vehicles, certain precautions must be taken such as removing a fuse, or turning on the defroster. The owner’s manual should spell out any precautions that must be taken.

03 of 03 Starting the Car With the Dead Battery First, start the car with the good battery and leave it running. If the battery in the dead was was really badly drained, it may help to leave them connected for a minute with the good car running before you try to start the dead car.  Turn the key in the dead car to start and it should fire right up. If you continue to have starting problems, you might need to install a new battery. You can disconnect the jumper cables right away. Disconnecting the Jumper Cables Disconnecting the jumper cables doesn't need to happen in any specific order, but be sure you don't let the red and black cables touch each other at the end when they are still connected to one battery. If the dead car doesn't turn over or turns over very slowly, check to see if your battery or connections are corroded. If they are, sometimes a little wiggling while the cable clamp is connected will make your connection better. Otherwise, it might be a good time to clean your battery connections. If your car still does not start, see the no-start checklist.
