You should check your 24V transformer for power, Using the AC Range on your meter.
Sounds like the transformer is not getting power or is bad, or you have a broken low voltage wire conductor.
Do you understand Jim's wiring diagram ?
P.S. Ground has nothing to do with it, It is AC not DC like you may be thinking.
