I have a bobcat s205 skid steer. While loading up some feed into the wagon last winter, i put the bucket down, left the machine running and went to feed. I came back hopped in to load again and the bucket would not engage, i could move forward and backwards but could not move the bucket, after about 3 or 4 minutes the machine would shut off. It would flash me a code L7404. "Gateway controller no communication". We have tried switching relays and it works for about 5 minutes and then locks out the controls again. We are at our wits end and need this loader operational for feeder calves coming this October. Does anyone have any ideas how we can fix our problem without breaking the bank? I appreciate any help in advance!
