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

If you have a drip leg near generator open that up for a sec and then try it again.

i have a Kohler 16 Magnum opposed cylinder engine and it wont crank over with the spark plugs in it,battery and starter are both good,its an aluminum engine and i have seen several of the Kohler engines break the automatic compression release on the cam gear and they seem to lock up while trying to start,pull the plugs and the crank fine,Kokler is the most expensive engine i have seen and their parts are outrageously priced,old Kokler was a good engine,newer ones in my opinion are junk,i work at a small engine shop,i have seen new Kohler engines with a broken ACRs,i work at a second job,we got a new supervisor that worked for Kohler before her came to our plant,he said he worked customer service at Kohler and he heard complaints constantly from people using their engines and the returns were out the roof on their engines,what im saying is i wont ever but another Kohler unless itsm an old one,Thanks Tommy
