If you do Google search for "ninja 250 new-gen wiring diagram", you may find 'library of manuals' with PDF of new-gen service manual. I think page 376 may have diagram you're interested in.

So test for +12v starting at battery's positive and test every junction on way to light bulb. Turn ignition switch ON to test power after switch.

Similarly, test ground side of circuit. Starting from negative terminal of battery out, all junctions should have fully continuity/zeros ohms and direct connection to negative-terminal of battery. Work your way to ground connector at bulb-socket.
