Battery Negative Cable Replacement Negative Battery Cable to Battery

When replacing battery cables, use a replacement cable having the following specifications the same as the original cable:

    • Type of cable
    • Diameter
    • Length

Additional feed wires may be attached to the positive cables and additional ground leads may be attached to the negative cables.

Notice: When installing the positive battery cable to the starter solenoid, the inner nut on the solenoid battery terminal must be tightened before the battery cable and the other leads are installed in the vehicle. Failure to do so will result in damage to the solenoid terminal and/or the solenoid.

Always route a replacement battery cable the same as the original cable.

    Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

  1. Disconnect the negative battery cable from the battery. Refer to Battery Negative Cable Disconnection and Connection .
  2. Disconnect the negative battery cable from the frame.
  3. Disconnect the wires from the negative junction block.
  4. Disconnect the negative junction from the frame.

Installation Procedure


    Object Number: 204733  Size: SH
  1. Connect the negative battery cable to the frame.
  2. Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  3. Clean the grounding area and coat the area with a copper-impregnated ground sealer.
  4. Tighten
    Tighten the cable to the frame bolt to 30 N·m (22 lb ft).

  5. Connect the negative junction to the frame.
  6. Connect the wires to the negative junction block.
  7. Connect the negative battery cable to the battery. Refer to Battery Negative Cable Disconnection and Connection .
