Which condition should you verify when inspecting a bus battery compartment?
Correct answer: C. – The connections have no excessive corrosion, and the box and its cover or door are undamaged and secure
The battery must be secure, its connections must be tight, and its cell caps must be present. The connections should not show excessive corrosion. The battery box and its cover or door must also be secure and free from damage so that the compartment is properly closed.
