Q: How to remove and replace battery cables on Ford Fusion?
A: Always disconnect the negative battery cable first and reconnect it last to avoid shorting the battery. Even when replacing the positive cable, disconnect the negative one first. Trace and disconnect old cables from both ends, noting their routing for correct installation. If replacing, buy identical parts using old cables as reference. Clean solenoid or ground connection threads with a wire brush and apply corrosion inhibitor. Attach the cable securely to the solenoid or ground. Ensure new cable reaches the battery post without stretching before connecting. Connect to the positive terminal first, then the negative.
