I have a Case 621 D we use it mostly in the snow. I went to get it ready for transport back to the shop for maintenance before the season starts. when I got there the unit wouldn't start. it would turn over but not start so I diagnosed it to the fuel shut off. I replaced it. it started just fine the I went to move the unit I noticed the dash dosn't show any thing unless I hold the reset down for more then ten seconds. when I let the reset go it gose back to nothing. then I checked the controls for the boom and bucket they are not working. I can put the unit in forward and reverse it beeps in reverse but it wont move any Ideas I have checked the fuses and relays they all seam to be in tak. oh yea one more thing if I turn the lights on it beeps at me like the unit is turned off.
Check your tail lights. If one is broken or burnt out it you cant move.
I did not know that I will check them today
Ok I figured out the problem do to a mouse some of the wires were chewed on the back of the relays so I fixed the wires and now the loader will do what ever I ask thanks for the help. just in case some one else has this problem the two relays were the bottom two on the right hand side.
Good to hear you found it. Mice can create interesting problems.
