  2. See Figure 1. On FXCWC model, lift battery cover from frame and remove.
  3. See Figure 2. On FLSTSB model, remove frame fairing.
    1. Remove thumbscrew from frame fairing.
    2. Lift rear of frame fairing. Raise fairing over the seat spring mounting pins.
    3. Pull fairing to the rear and remove.
  4. See Figure 3. Unthread bolt and remove battery negative cable (black) from battery negative (-) terminal.
  5. Unthread bolt and remove battery positive cable (red) from battery positive (+) terminal.

Installation and Connection
NOTICE
Do not over-tighten bolts on battery terminals. Use recommended torque values. Over-tightening battery terminal bolts could result in damage to battery terminals. (00216a)
WARNING
Connect positive (+) battery cable first. If positive (+) cable should contact ground with negative (-) cable connected, the resulting sparks can cause a battery explosion, which could result in death or serious injury. (00068a)

Do not allow positive (+) battery cable to contact ground with negative (-) cable connected. Resulting sparks can cause a battery explosion, which could result in death or serious injury. (00069a)
1. Place the fully charged battery into the battery box located within oil tank cavity, terminal side forward.
2. Attach battery positive cable (+) (red) to battery positive (+) terminal.
3. Tighten fastener to 6.8–7.9 N·m (60–70 in-lbs).
4. Attach battery negative cable (black) to battery negative (-) terminal.
5. Tighten fastener to 6.8–7.9 N·m (60–70 in-lbs).
