The schematic shows the secondary of the tuning coil #2 to be progressively wound and tapped for the bands. As the bands increase in frequency there is fewer windings less resistance. Therefore using a ohmmeter can detect what wires go where. The same is relatively true for the two other coils the antenna input and the oscillator coil.
If there is no "feeling" of a detent the likely the detent ball is missing or a friction blade has broken, repair as needed or go to Classifieds and post a WTB for a band switch for this model.
Any of the coils could have poor connections or open windings, so if reading the full length of the coil is open locate the open coil and either rewind or request in the classified for a Wanted to Buy.
Though this chassis is used in other models because it is a "Waltons" chassis expect a premium for the part(s).
