...when I'm cranking with the hand crank, absolutely nothing happens...
not to be argumentative but, NAH...seems to me that the "Cable" was probably only the "Height Limit Cable"...they're non-electical, non-structural...just an exact length of cable to determine the maximum height to raise the roof...easily replacedIt sounds to me like when you purchased it, the previous owner was using the electric winch and allowed it to raise too high. This has not happened to me, but my guess is one or more of the cables has come loose and is not connected to the frame. This is not a battery problem but a structural one. Does anyone on the forum know how to reconnect such cables or what to look for. I think that would help.
