[QUOTE="landshaper, post: 65096, member: 9016"] Hi all, I'm at the end of my rope with this thing. It's a '99 773 with the electronic hand controls (ahc). Here's what it does: some days- works fine all day; other days- when I try to lower the bucket nothing happens, and then it will not lift/lower/tilt up/tilt down any more until I shut it off and then restart the machine. It is totally an intermittent problem, which is what is driving me insane. I have checked the actuators by removing them and switching them. It still happens only during bucket lowering so I believe I can rule that out. I have checked the hand control switches by swapping the plugs on them, and then the opposite switch makes it fail. Also, when I turn the machine on, the error lights do not function correctly. The left light (the indicator for lift) never turns on at all... ever. The right light remains on when the machine operates, and sometimes flashes (3 flashes) when the machine stops functioning. I have checked the connections and fuses several times, however, I still do not quite understand the wiring of it. Additionally, the previous owner hired a mechanic to troubleshoot this problem, who indicated that it is "probably the computer". At this point I believe he may be correct, but they seem to cost $1500 so that is the last resort attempt. I hope someone can help, as there is no dealer on this island.... Thanks. [/QUOTE]
