Which component is NOT typically tested on the AECTS?

• A. Generators
• B. Generator drive systems
• C. Hydraulic pumps
• D. Engine driven accessories

Answer: (C)

AECTS focuses on electrical power generation, drive, and the electrical system’s accessories. It’s used to verify that the generator, its drive gear, and engine-driven accessories that interact with the electrical system function correctly, providing proper voltage, frequency, and control. Hydraulic pumps are part of the hydraulic system, not the electrical system, so they’re tested with hydraulic test equipment rather than through the electrical test station. Therefore, they’re not typically included in AECTS testing. If a hydraulic pump is mounted on the engine’s accessory drive, it may be driven by that system, but its testing belongs to the hydraulic side, not the electrical test setup.
