Could be lost exciter current. This is how to restore it - Connect 16 or 18 gauge wires to a 12 volt battery. With generator running, insert bare ends of wires into AC outlet - one to Hot, the other to Neutral. Insert and remove quickly. There should be a flash and power will be restored. If not, repeat until you get that flash and output current restored. Using light gauge wires is so that if you are too slow to remove them once AC is restored. they will burn out before the battery suffers from the AC incoming. Be quick and be careful.

have the voltage regulator system checked
in the regulator the voltage controls the amperage allowed and it that unit is not working properly then there will be no current out put
that regulator could be part of the control board for the main ac out put and may have developed a fault in the section for 12 volts on the board
there is a limit on the charge rate for the battery and if it is exceed it may have damaged that circuit or possible blown a fuse in the amperage circuit

Had the ' engine m/n invalid shut down on my 12resv Kohler generator. Off light was blinking red. Clicked the select button 3 times to clear fault and confirmed Y ...then went to the Gen set information which is a few more menu down with the arrow button. It did say 12Resv so had it blink and rest it but same thing. so rest fault again and went back to the gen set information tab and I changed it to 14resv and all cleared without out fault and tryed to hit run for a min . Ofcourse it's wrong model number so would not start but did not fault. So I went back to the Gen set information menu and put it back to the original 12Resv and it started right up without fault. I placed back in Auto and been working ever sense. Has friend had same problem and as with mine it happened on a night where power went on and off multiple times. Think its really just loosing informsiton to recognize the unit to controller and needs reset or flashed if you have the OnCue will work as well....one more thing good idea I'd not sure your battery is good over 12v to pull terminals and physically check with a multi meter should be liek 13 4 volts or so for optimal starting. Good luck this was a head ache and see others have had problem ..tony Michigan
