i purchased a Cyclone p with a fanuc 21iT control, all is good apart from the previous owner let the batteries die! no backups or data sheets

its taken a year but i'm nearly there, got it running a simple job last night, but i have had to short out the axis lube float switch because the alarm is permanently on, and the spindle still runs when the program reads M00,
does anyone have a list of keep relays?? i realise there may be differences between machines but it may give me some info to work on.
i have the machine in my garage and i am currently making a large scale traction engine, hopefully this machine will help me with the bolts and studs, i hate making repetitive parts on manual machines!!
all the best,
Chris.
