I have a new S330 and the first time I tried to use the auto bob tach it did not work. The dealer is going to make a house call and find the problem. But I was wondering if anyone has had this problem. The dealer said it could be a fuse because the hydraulics is not making a sound, not pressuring up or anything. It's like it is not getting the signal. Anyone know which exact fuse runs the bob tach??? Any help would be appreciated. As you can tell I am a first time skid steer owner and am learning as I go. Thanks in advace.
