Demountable camper group

Hi,

I have recently purchased an used Northstart demoutableand I am slowly learning about it.
The camper came with a set of Happijac legs and ones on the left side work with the remote while the ones on the right side do not and need the manual crank to get them up and down.
The model on the control unit is 600501F.
I did a quick search and could not find much about it.
Has anybody got experience of troubleshooting this kind of equipment?
Would it be quite safe if I moved the cables to the working side of the controller to if the error stays or moves with the motors?
I would think that would be a good strategy, but I prefer to ask first...

Thanking youin advance

Dom
