Lost RA Drive on my CGEM 800
      #5570007 - 12/13/12 09:42 PM

I set up my C9.25 this evening only to find the RA drive motor isn't working. No slew,no whiring. The declination drive is fine. I rebalanced the setup and adjusted the clutch without effect. How does one trouble shoot this situation? The mount is only about one year old.

Remove the control panel and swap the connectors on the motors and see if the RA works.

Stan,

Good idea. I had a chance to look at the symptoms since my initial post. I found that the RA will slew counterclockwise (from Polaris point of view) while straining but will not go clockwise independent of how I balance the mount.

Thanks

Now that sounds mechanical in nature, rather than electronic. You can try backing off the worm gear adjustment on the RA axis to see if it's a binding problem of the worm gear/ring gear.
