Question

Quizplus · Accepted Answer

Disconnecting the battery ground cable is a standard safety procedure to prevent electrical shorts and other issues when working on a vehicle's electrical system. Using a fusible link that is larger (lower gauge number) than the circuit it protects is incorrect because the fusible link should be of the same rating or slightly lower to ensure it burns out before the wiring of the circuit it is protecting does, preventing potential damage.
