MD-83 advise

RIght generator trip followed by a AC x-tie lockout. Rt Feeder fault annunciator illuminates. Reset of GEN ok. We have this glitch come and go, intermittent. Ran all the AMM t/s tasks, wiring checks, ohm readings,
ct checks, replaced GCU, Relays. Not able to duplicate on the ground. Anybody ever see the GEN ever cause? Getting down to the point
to buy a generator.

If you have any Current Transformers monitoring the feeders, check them out - rare but they do fail and will give " short to ground " type failure indications. Otherwise, check your generator terminal posts.
