I get a ot100 alarm

OT usually means over-travel. Maybe your spindle axis has moved out of working limits, or you have a faulty limit switch..

I don't have my book here for the spindle alarm 4.
The OT100 is just indicating the spindle is in an alarm condition.
Check as much of the power supplies you can, including control fuses etc,
Also see if you can find the test pins marked with +5, +12, or +24 etc, as there are often regulator IC,s in board, check with ref to the 0v pin.
I may be able to get the code tomorrow if you still need it.

Al,
Thanks for the help, I am not having any luck. If you can find the code tomorrow, it would be greatly appreciated. Justin
