How to Install a Ford F250 Battery Cable Replacement

by Tara Kimball

Damaged battery cables can restrict your vehicle's ability to charge the starting system. You should monitor your Ford F-250 battery cables for signs of wear or damage. Check the cables at every oil change and replace them any time you notice cracking or corrosion. Buy replacement cables for your truck at an auto parts retailer or Ford dealer and change them yourself to keep your truck running at its best.

Step 1

Open the hood of the F-250. Loosen the negative battery cable from the terminal with a wrench and secure it away from the battery.

Step 2

Loosen the cable on the positive battery terminal with a wrench. Remove the cable from the battery. Clean the battery terminals with a terminal brush to remove any residual corrosion or rust.

Step 3

Follow the negative cable to the opposite end where it mounts to the grounding point. The F-250 negative cable grounds to either the frame or the engine block. Remove the retaining bolt with a wrench to remove the cable. Install the new negative cable and secure it with the retaining bolt. Tighten the bolt with a wrench.

Step 4

Trace the positive battery cable to the starter. Remove the nut securing the cable end to the starter with a wrench. Remove the old cable from the post. Install the new cable and secure it with the nut. Tighten the nut with a wrench.

Attach the positive cable to the battery. Tighten the connection with a wrench. Repeat the process with the negative cable. Close the hood.
