Controller Troubleshooting

I have a Rainbird controller that has suddenly stopped working. I cannot get it to work in manual mode or anything else. Tried resetting it, bypassed the rain sensor, nada.. The GFCI plug was thrown last week so i suspect the controller is hosed. Trouble shooting steps.
  1. Reset controller and reprogrammed -nada
  2. Water is on
  3. Voltage at plug good
  4. Voltage through transformer is 29.4
  5. Manually/physically turned on 3 valves (at the valve itself) and all worked fine
  6. Returned to controller and Turned zone 1 on manually and tested voltage - 29.4
  7. Turned zone 2 on manually and tested voltage - 29.4
  8. all the way down the line
  9. Then noticed that when zone 1 was on manually.. every other zone was still showing 29.4 voltage.
I figured that should not be right put wanted to confirm before i bought a new controller.
Thoughts
Thanks

When you turn zone 1 on is the voltage coming out of the controller on the other zones or is it coming out of the wires?

If it's coming out of the controller.. Replace it.

If it's coming out of the wires then there's an issue with the wiring.

dumb question

So how would I know that, pull all the other zones wires and then test zone 1. Pull just the zone 1 wire and test it with COM? sorry learning quickly but learning

You could disconnect the common wire from the controller, turn on number one, now test the terminals again. Is only number 1 on or are they all on?

You could also disconnect all the numbered wires from the controller except number 1. Leave the common connected. Now turn on number 1 and test the controller and the disconnected wires. Or just disconnect one wire and test it while 1 is on. Is the voltage coming out of the wire or out of the controller.....
