by Editorial Team

If you find yourself not being able to start your car, then you may have a problem with your main battery fuse. After you have ruled out any possible problems with your alternator, check you car battery. If your battery connectors are clean and you have done nothing to drain the battery, then find and check your main battery fuse.

Step 1

Find your owner's manual. The best source to find the main battery fuse is in your owner's manual. Look in the table of contents or index to properly locate the fuse box.

Step 2

Open the hood of your car. Make sure that your car is in the park position, the emergency brake is up, and that you are in a safe location. Before popping the hood put a pair of rubber gloves on. Next, secure the hood with the hood prop. Remember that safety always comes first.

Step 3

Look for the fuse box under your hood. All cars are different and the location of the fuse box will vary. However, most of the parts under your hood are labeled or easy to locate in your owner's manual.

Step 4

Go over diagram. Once you have located the fuse box look at the writing on the lid of the fuse box. Most fuse boxes have a clearly labeled diagram that lets you know what fuses are under the lid. There will be a label that reads "battery" that has a number associated with it. The number represents the amps of the fuse. The number is what you will be looking for when you open the fuse box.

Step 5

Open the fuse box with a screw driver. Compare the fuse box diagram to the actual layout inside the box. The fuse box should be laid out exactly like the diagram on the lid. Each fuse will have a number printed on top of it. Locate the one that is associated to the battery and you will have successfully located the main battery fuse to your car.

Step 6

Change the main battery fuse if it has blown to get your car back on the road again.
