How To Replace 7.3 Powerstroke Positive Battery Cable?

Replacing the positive battery cable can be easily accomplished following the steps outlined below.

Required Tools
Basic sets of hand tools (Screwdriver, Wrench, Socket, Rachet, Nuts, and Bolts) Battery Cleaning Tool Heavy duty diagonal cutter New Cables and Terminals

Step 1:

Careful tracing and following both battery cables from the battery terminals to their point of connection on the vehicle is necessary to compare, select and obtain an adequate replacement cable. Furthermore, a universal line must be trimmed to the correct length with a heavy-duty diagonal cutter. This will ensure that you have obtained an appropriate fit for your vehicle.

Step 2:

Standard practice dictates that when replacing either the negative or positive battery cable, the black or negative marked terminal should be removed first to avoid potential electrical short-circuit shock accidents. To accomplish this, a wrench or screwdriver should disconnect said airport.

Step 3:

Tracing the negative cable to where it meets the vehicle’s chassis, then tracing the positive battery cable to where it connects with the truck’s fuse block should be done. It is necessary to use a socket and ratchet to loosen the negative groundnut to remove its grounding wire. It must be verified that it is clean or needs cleaning. The nut which holds down the positive (red) cable must be disconnected and removed from its position. Finally, pull out this same positive cable to complete this step.

Step 4:

The existing positive cable should be replaced with the new one, ensuring it is tightened correctly. The recent positive cable should then be slid over the positive terminal and securely attached to the battery. Finally, using a wrench, the positive terminal end should be tightened securely before reconnecting the negative terminal.

Step 5:

Now that the new cable is properly in place, it’s time to test if the issue has been resolved. Inserting the vehicle key and starting up should indicate whether or not the problem has been fixed.
