have you fixed it yet? If not, try the fuse in the top of the line filter (its a slo-blo fuse). The line filter is under the large access cover on top and at aprox. 11:00 o'clock position from the control handle. There is a small pastic grey screw cap and underneath is the fuse. When these blow, you will lose all aux functions, but it will travel and lift. If the fuse is good check the Over the mast cable at different positions, could be a bad spot in cable. Last look at control handle.
