New owner of a blue GM-100, S/N 0082.
Here's my problem: The RA motor works, and I can see the worm gear turn either direction, but the setting circle never moves.
The Dec motor worked last week, and I could see the belt move. Now it makes a clicky sound but the belt does not move.?
The 492 unit appears to be in solid working order. I have a couple other 492s, so I could swap one out and see if that makes a difference.?
The clutches work smooth and easy with no slop.?What should I check out next?
