A) ensure the circuit is de- energized, and then use an ohmmeter or continuity tester connected across the bottoms of the fuses |
B) ensure the circuit is de- energized, and then use an ohmmeter or continuity tester connected across the tops of the fuses |
C) apply a voltage tester diagonally across the tops of the fuses and the bottoms of the other fuses |
D) apply a voltage tester across the tops of the fuses |
