I dropped an RL02 cartridge, and needed to get it to load 
one more time to get programs off it.
The ready lamp was a dim, slightly flickering glow.  I 
figured the platter had been knocked off center.
I loosened the bolts at tapped it a bit until it looked 
better centered.  It took a couple tries, but then the ready 
light came on fully bright, and I was able to mount the disk 
and read it.

I don't know if that could be your problem.  If you get a 
solid servo signal with the motor disconnected, then this is 
not the same problem.
