I know you saw the relays working but are the contacts clean? Dirty contacts will not complete the circuit if they are too damaged.
The RCM seemed to be the cause of the trouble as noted in other posts.
Somehow I doubt your problem is as complex as you are making it, we can get carried away with our problems and end up not seeing the woods for the trees.
