Wild guess
Since your other valves work with the same ohm and volt readings I'm not concerned with that at all. Personally I've never installed this valve. I've never seen it installed. A RainBird jartop is a rare sight around these parts. It sounds like some debris is clogging a port. Also, is there a valve right next to it? If so,switch solenoids and wires and see if it comes on. If it comes on by switching solenoids from another valve that works then you have a wiring problem. Check all your connections. What happens when you put the solenoid and wires from the valve that doesn't work onto a valve you know that works? If that valve comes on again I'd say something's clogged. If not it's the wiring. Is it new and installed backwards? That's a good start. Good luck!
If I can't fix it, it's broken!
