Given the work you have done, you never mentioned if you have had the stator and rotor tested? if you can get it running check for DC power on the brushes. that will help isolate. If power blinks for a second, that is the control trying to flash the rotor, if the rotor has a short the controls will remove the excitation voltage. Check that before going to any major expense

OC is Over Crank which generally means it cranked and cranked and failed to start. Turning the switch off and on again is the way to clear the fault. How long is it taking to start whilst cranking? It should start within 8 seconds

Is the battery system charged, normally a totally dead display is indicative of a dead DC circuit, check control board fuses also. Also have an electrician check the AC control fuses normally in the transfer switch.

Aux fault is caused by a momentary loss of voltage from the speed sensor or low coolant level sensor. I would suggest you investigate both for possible cause.
If the unit has a low coolant level sensor you can find it near the top of radiator, small two wire plug. Disconnect and see if unit runs. make sure radiator is filled to over flowing before testing to eliminate this as the cause. Just because you can see or feel the coolant is not enough, fill to overflowing is the key.

no 14vac coming from generator to control board.--cause can be regulator board on end of generator---dirty brushes or worn out brushes==b1 and b2 winding open that outputs the 14vac--my problem was blown regulator board

the chirping you hear is probably from a worn cam or valve lifter.
usually these engines use an oil slinger to throw oil around the crank case.
if the oil gets too low parts will wear away faster.
sorry to say but your engine has probably had it and is due for a rebuild.
always keep the oil at sufficient level and change it regularly
