5. Loosen the four captive screws (figure 6, item 1) on the fuse box cover (figure 6, item 2), and remove the
cover from the fuse box (figure 6, item 3).
Replace or repair components only after the affected circuit has been secured,
locked out, and tagged out. Performing replacement with the circuit energized
may result in serious injury or death.
6. Take voltage readings with a multimeter on both sides of the fuses (figure 6, item 4) to ensure that electrical
circuits are deenergized. If voltage is present, ensure that the proper switch is OFF, locked out, and tagged
out (FM 55-502) and that the correct ROWPU battery terminals are disconnected. If no voltage is present,
proceed with the procedure.
7. Remove the fuses (figure 6, item 4) from the fuse box (figure 6, item 3).
