    For manoevering in confined spaces, single-handed, via RF R/C hand unit
    Assuming no one would happen to have the schematic for one. Would anyone
    know what the safety logic/inter-lock around the swivel-out/in motor systems
    is. I understand it makes sure the caravan cannot be driven off while these
    drive units are positioned against the caravan wheels, somehow connected to
    the caravan brake light wiring.
    Also what to look for in the way of overcurrent to those motors (or even
    the main drive motors) as there sems to be no predetermined positioning of
    the swivellers but seem to move out until some sort of good contact with the
    tyres is made.

    I suspect this safety/brake-light circuit that should return to the caravan
    12V battery was returned to car battery at -12V, would that be possible ?.
    So 1 amp rating diodes survived but 0.1x .45mm pcb track ruptured , which I
    calculate about 3 amp fusing current.
