I am currently facing a challenge where my APU generator OUT light comes ON, but the frequency and voltage is with allowable limit, also, there is load indication. We have changed the contactor, Voltage regulator and the even the APU regulator but the discrepancy persist. Pls I will appreciate any quick response . Thanks

In the c130j aux sys when you turn off the aux pump pres is trapped in brakes, between check valve and brake control valve on one side and the check valve and brake selector valve on other side. But where does the pressure before going into the brake check valves bleed off at? For booster sys you have to move the flight controls because pres is trapped and for util sys you have to move flight controls and bleed brakes because pres is trapped, but why isn't pres trapped in aux? Where does it go? When using the hand pump pres bleeds off, you can see it in the direct reading gauge going down, but it stays in the brakes. Where is the pres bleeding off at?

Pls can someone advice on what to do if one of the engine generator phase is indicating low voltage and zero frequency, while others phases (A&B) indicate the correct voltage and frequency. The line contactor was replaced, the fuse at the upper electrical panel at FS 245 was ok, new generator installed, new voltage regulator was also installed, yet the discrepancy persist. Kind help provide any assistance. Thanks
