2320 no start,electrical

Just touching base with anyone who may have run into a intermitted no crank/no start on a 2320 tractor. Mine has had no issues,cut grass,parked it and last night no start. No crank signal from ignition on starter s terminal,bypass and starter cranks engine fine,no start. Suspect no voltage to fuel shutoff. I have a cab on so spend the better part of the evening getting to relays under steering column and without repairing anything ,it starts and runs!!!!
I do not have a service manual but i do see three relays there i though i read there is a fourth? I suspect bad relay and with me jiggling and moving things around it now works.. My question is there 4 relays and is there a main relay that would control power to s terminal on starter as well as fuel shut off?
