The load management system responds to voltage drop by performing which action?

The load management system responds to voltage drop by performing which action?

• A. Shed electrical load in a predetermined order.
• B. Increase voltage to the chassis.
• C. Disengage the transmission from the engine.
• D. Open the fuel injectors.

Answer: (A)

When the electrical system detects a voltage drop, the load management system protects the critical functions by shedding nonessential electrical loads in a predetermined order. This means it automatically disconnects or power-sizes off devices that aren’t immediately needed (like noncritical lighting or accessory circuits) so the battery and the essential systems—such as the pump controls, primary lighting, and communications—can stay powered and the voltage can stabilize. Once voltage returns toward normal, the shed loads can be restored in the proper sequence. This approach isn’t about increasing voltage to the chassis—that’s handled by the charging system and regulator, not by shedding loads. It also isn’t about mechanically changing the transmission or fuel injectors; those are engine-control functions, not responses to electrical load management.
