Hello. I have a 2004 T200 without ACS. Was digging a pool back in June and when I got back from lunch the left panel said door and had a code of 78-74. Of course lift and tilt were then locked up. I haven't had the door on this machine since I bought it in 08. I have the door but it does not have any kind of plug on it anyway. Next morning it worked again. It was intermittent for a while with the bucket getting locked up in the air sometimes. Then it started working a lot better for a month or two. I parked it for a couple of weeks and have not been able to use it since. The door code sometimes will flash off and right back on but not for more than a second or two. Sometimes it will go haywire and flicker and off and on and you can hear the spool lock solenoids clicking. I have been having to rent a machine for 3 days now and try to find whats going on with mine at night. No luck. Any suggestions?
