Error Code 50-56
Well, after 2 weeks at Bobcat, they thought they had solved the Error 50-56 code by replacing the wiring harness that goes from the dash to the 7-pin connector on the loader arm. They claimed there was a rub on the harness at some point. I have no reason to doubt them but I haven't seen the evidence, yet. Anyway, got it back to the ranch and was raking hay at about 8 mph when all of a sudden it came to a sudden stop. The weather was hot, I had the A/C on and it's dusty so the machine was working hard and hot but not overheating by any stretch. I let it rest for a few minutes, cleared off the dust from the rear radiator cover while I was waiting and replaced Fuse 4. Tried to restart it and it immediately blew Fuse 4 again and gave Error Code 50-56. So, we switched the rake to another machine and let the machine sit there for the rest of the weekend. I was getting ready to winch the unit onto a trailer the next day and I decided to try another 20 amp fuse in Fuse 4. I started it up and it loaded without issue. At least it saved me the time and effort from loading a dead machine. Anyway, it's heading back to Bobcat tomorrow for them to continue troubleshooting.
I don't recall whether the machine was hot the first time I encountered this issue but, at least this time, it didn't blow Fuse 4 when the machine was cold. When I say cold, I mean Texas cold. It was 90 degrees outside when we were loading it and it hadn't been run in 24 hours.
A little history on the unit, during some extended off season time, a rat got into the machine and chewed the main wiring harness literally in half. I had the entire wiring harness replaced with a new one at significant cost. Worked fine for about 100 hours. Then 50-56 started showing up and it blows Fuse 4.
I was very skeptical and have told them about the posts about the faulty wiring harnesses that others have experienced but they seemed determined to do it their way.
I'd be very interested if anyone else experienced a similar failure.
