1) Put a voltmeter on the solenoid terminals and see what the control signal supply voltage is. It could be AC or DC.
2) Go back to the control signal source and trace the wires until it becomes apparent what the control signal voltage is.
3) Dig out the electrical drawings and see what control signal the circuit was designed for.
4) Measuring winding resistance is dicey (not terribly reliable) because the wattage ratings on solenoid coils covers a range of about 3:1, so the difference between a DC coil and an AC coil, or between a 6 or 9 watt coil is overlapped by different wattage coils for different services.
