Q: How do you disconnect the battery on Lincoln Navigator?
A: To disconnect the battery, first remove both cables, starting with the ground cable to avoid shorting. Remember, the vehicle may need to be driven 10 miles after reconnection for smooth operation. Next, remove the bolt and wedge to lift out the heavy battery, using lifting straps if needed. If necessary, remove the battery tray bolts for component access. Reinstallation is the reverse of removal.
