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

Kindly check the wiring of auxiliary switching contact of the K-53E and GCP (PIR).

Sounds like a bad GCP: internal (PIR) or internal TR... Make sure your GCP is the same manufacture as your generator; ALSO make sure the GCP is fully seated in the rack and might want to "adjust it" with a quick hit/rap/ wack to get all the connections to make good contact.   SWAP with one of your Eng Gen CGPs to be sure.

Sir When the  load of generator was observed satisfactory in every  operation checkout of the system it is malfunction of GCP (PIR)  wiring.
