2. Remove the junction box cover (figure 1, item 2) from the junction box (figure 1, item 3).

WARNING

Death or serious injury can result from contact with live electrical circuits. Before

beginning work on this, or any other electrical circuit or equipment, make certain

electrical power is OFF, locked out, and tagged out (FM 55-502).

3. Using a multimeter, check for available voltage at the wire nuts (figure 1, item 4) in the junction box (figure 1,

item 3). If voltage is present, check that the proper circuit breaker is OFF, locked out, and tagged out

(FM 55-502). If no voltage is present, continue with the procedure.
