Rusty,
I assume that you are powering it from a limited source, like a trickle charger? If so, the vibrator or something downstream is shorting and the charger is probably at the max or tripping off on overload. Those solid state vibrators must be powered with the correct polarity or they will not work and probably will get damaged. If you remove the OZ4 tube, which is the rectifier, and you get the same result, it is very likely the vibrator is shot. If on the other hand the tube, which I think would be the 6V6 lights up, then the problem is further downstream than the vibrator. If you want to try that test, I would be interested in the results.
