Spindle in fault condition?

I have been running a Fanuc 18MA as normal with no problems until a couple of hours ago. It stopped mid program and gave me a "Router in feedhold due to fault in spindle 1 circuit. Possible causes: Low coolant flow, (Coolant pump may be off), Spindle drive may be in faultstate, or spindle has overheated", which typically only comes from not having our chiller switched on in the morning. After checking the chiller and the Ladder I have found that SPAFLT is not making connection which I am told is a relay for the spindle. The machine starts like normal but once the spindle is activated it, it faults out. The company maintenance man and myself are having an impossible time finding which of the 5 relays are routed to the spindle yet we have noticed that 2 of them are quite hot to the touch. Any help, advice, ideas or comments are greatly appreciated as this is a very inconvenient time for this router to be out of commission. Thanks!
