Belts intact?
Interlock switch good?
Take the bottom cover off - can you spin the pack by hand? Ie, are the
spindle bearings free?
IIRC, the RK05 will spin a pack w/out being connected to anything, as
opposed to RL0x drives that want to see valid clock coming from the
controller. I could be mistaken about this - my RK-experience is nearly 5
years old now.
Ummm... also ISTR a fairly large relay back near the linear actuator that
turns the spindle motor on... is this clicking?
Time to get out the Volts Guesser and a handy Schematic....
