Generator Sets
6.3.1 Issue: The voltage regulation system for the MEP-804A, MEP-805A, and MEP-806A Tactical
Quiet Generators can fail in a mode that heavily damages the main alternator windings,
causing the generator set to be Non-Mission Capable until the alternator and other
components are replaced. This modification adds a fuse into the excitation circuit to protect
the main alternator from damage.
