    Connecting the probe between the green and yellow wires I am starting to see some blips on the scope. My gut is seeing the GREEN as being an isolated SPST switch circuitry Whereas, the Hall related circuitry is separate . . . put scope grounding clip to BLACK and expect pulse outputting...

    I would try the simplest possibility first. By hooking up AC metering mode between the Black ground and Yellow pulse out wiring and manually slowly rotate the impeller to see if there is outputting. Or actually, just try both of the loose rod magnets ends to come up to and move away from the...
