I have a 7.3 Kohler Generator and having issues all summer. I have been getting the UU code all summer which indicates low voltage. Started there, battery checks out. Checked the impeller that is fine. Well last night after about 20 tries it started. It was was running good so after about ten minutes I put a load on it. It ran good for about another 5 minutes then stopped and came up with a code of EC69 which indicates a oxygen sensor. I tried to start it again for another 10 minuted and the UU code keeps coming up. From what I have been reading the UU code can mean just about anything . Someone said try spark plugs. Anybody have any ideas?
Thanks
