Battery Cable Negative

Removal Procedure

Whenever battery cables are replaced, always be certain to use a replacement battery cable that is the same type and length. Some positive cables have additional feed wires attached to them and some negative cables have additional ground straps attached. Always be certain when replacing a battery cable to route it the same as the one being replaced.


    Object Number: 103330  Size: SH
  1. Remove the negative battery cable from the negative battery terminal. Refer to

    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.

    in General Information.

  3. Remove the negative cable ground bolt and the negative cable ground washer.
  4. Remove the ground strap.
  5. Remove the generator. Refer to Generator Replacement .

  6. Object Number: 103367  Size: SH
  7. Remove the nut, washer, and cable from the bolt.
  8. Remove any clamps or retainers securing the negative cable to the body.
  9. Remove the negative cable from the vehicle.
  10. • Note the routing.
    • Route as noted during the removal.

Installation Procedure


    Object Number: 103368  Size: SH
  1. Install the negative battery cable to the vehicle.
  2. Important: Route the negative battery cable over and through the generator support bracket.

  3. Install any clamps or retainers securing the negative cable to the body.

  4. Object Number: 103367  Size: SH
  5. Install the negative cable, washer and nut to the bolt.
  6. Tighten
    Tighten the nut to 34 N·m (25  lb  ft).

    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.

  7. Install the generator. Refer to Generator Replacement .

  8. Object Number: 103330  Size: SH
  9. Install the ground strap.
  10. Install the negative cable ground bolt and the negative cable ground washer.
  11. Tighten
    Tighten the negative cable ground bolt to 4 N·m (35 lb in).

  12. Install the negative battery cable to the negative battery terminal.
  13. Tighten
    Tighten the negative battery cable to 17 N·m (13 lb ft).

  5. Remove the generator lead nut from the generator.
  6. Remove the positive battery cable bolt.

  7. Object Number: 103434  Size: SH
  8. Disconnect the positive battery cable nuts from the starter solenoid switch and electrical center.
  9. Disconnect the positive battery cable from the starter solenoid switch and the electrical center.

Installation Procedure


    Object Number: 103438  Size: SH

    Notice: Before attaching the field lead, be sure that the starter solenoid terminal is secure by tightening the nut next to the cap. This only applies to SD-260 and PG-250 starter motors. If this nut is not tight, the cap may be damaged during installation of the field lead and cause the starter to fail later.

  1. Tighten the solenoid battery terminal nut.
  2. Tighten
    Tighten the solenoid battery terminal nut to 10 N·m (89 lb in).

    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.
