Hello,Please can anyone help.The spindle on my Orac has just stopped.Checked out the obvious but no luck.Any help appreciated.
Thanks

Have you tried to force the spindle to run by linking the run command input on the spindle drive ? This will eliminate any interlocking (eg guard switch) issues - that is, if the Orac had any ?

I believe this is your spindle drive :

Another link that may be of use:
viewtopic.php?t=459

Thanks for that.No interlocks fitted,any thing else

I'd definately go down the route of getting the drive to run by linking the run / enable with your own switch (4,5,6) and a pot on the speed control pins (1,2,3)
If that works, then you'll be looking for old, broken or corroded wiring is my guess.

I presume you've found and checked all the fuses ?
