Ford F-150 Battery Cable

Possible Causes of Your Ford F-150 Battery Cable Issues

Your battery cables are usually left unnoticed until your Ford F-150 starts losing power and becomes difficult to start. However, having faulty battery cables can be just as problematic as damaging the battery itself. Just like any other component in your vehicle, your battery cables start to get worn out over time. Since damaged battery cables can result to a sudden no-start issue or an engine that dies on you in the middle of the road, it is very important to know the main reasons behind their failure. Here are some common causes of Ford F-150 battery cable problems:

Starting trouble

Due to constant vibration in your engine bay, your battery cables can become loose and cause starting problems for your pickup. If it takes you several tries to start your engine and your battery, ignition coils, starter, and other ignition-related components are fine, then you should try checking for a loose connection between your battery cables and terminals. If corroded terminals are causing the loose connection, they will have to be replaced.

Loss of power

If your pickup is experiencing a sputtering engine accompanied by intermittent operation of other electrical components, then there is a chance that you have issues with corrosion in your battery cables. Corrosion usually starts along the terminals but can eventually eat up the copper wires inside the battery cables as well. Even though the battery cables might appear fine on the outside, terminals that show extreme rust usually means that the cables are also corroded. If you find some red or green discoloration along the cables, then it's time to replace them.

Other troubleshooting tips

Since corrosion is one of the main culprits behind battery cable problems, it is also important to check for acid leaks in the battery. Acid leaks can seep from the battery terminals into the wires and causes starting issues and loss of power as well. If your battery cables keep getting loose, you should also see if your battery is securely mounted in your engine bay. Tighten any bolts or clamps that hold the battery to lessen the instances of loose battery cables.

  • Tips for a Longer-Lasting Ford F-150 Battery Cable

    Each Ford F-150 battery cable is vital in providing your engine with enough power to start and continue running. However, these components will still get worn out over time and require replacement. To lengthen the span of time between your battery cable repair jobs, follow these tips:


    Keep your battery cables clean and rust-free.


    Making sure that your terminals and battery cables don't get too dirty and corroded can definitely extend the lifespan of the cables and the battery itself. Corrosion on the terminals and battery cable clamps is pretty easy to spot, since these parts are much more visible. You can try cleaning these areas with a stiff wire brush and some baking soda paste. Don't forget to check for corrosion on the cables by looking for some red or green spots on the wires. This means that the copper wires inside the battery cables are corroded and that the cables need to be replaced.


    Regularly check for loose battery cables.


    From time to time, the connections between the terminals and the battery cables become loose resulting in poor conduction of electricity. Try to see if your battery cables are still properly and tightly attached to the terminals and tighten the cables as needed.


    Always disconnect the negative battery cable first when replacing your battery cables.


    Disconnecting the negative battery cable first not only protects you from shock, it also guards your car battery against a short circuit. Your F-150 typically has a black negative battery cable and a red positive battery cable. However, it would be advisable to read the markings first in case the colors where changed by a former owner or during a previous battery cable replacement.


    Replace the clamps together with the battery cables.


    While you can get separate battery cable clamps in most auto parts stores, it is still much more worthwhile to replace the cables when you replace your clamps. Since corroded clamps are usually accompanied by rusted battery cables, replacing them in one go can save you a lot of time and effort. Also, clamps that come with the battery cables offer a better fit and a more secure connection.
