I agree with MisterBill that is is not wired anything like the circuit in your first post. The pictures are not very helpful as there is no one picture with all the components together so we can follow the wires. The picture of the switch shows it is fully cross connected so there is no way the limit switches can each stop the rotation in only one direction. The resistance tests 1 and 2 show that there is no direct connection between the supply negative and the common terminals on the limit switches as shown on your circuit diagram. (Also I asked for you to have both limit switches activated. For example using sticky tape or an elastic band. ) I suggest that you re wire it from scratch ticking off each wire on the diagram as you connect that wire.
