Hi John,

?

I have just repaired a mount with exactly the same symptoms you describe.

In my case, it was the encoder pickup in the back of the high torque servo motor that was faulty.

Luckily the optical shaft encoder pickup was available from RS Components and was relatively easy to replace.

?

Not sure if you have the same motors, but it would be worth checking.

Hello all, New member here, with a problem.

Ok, I just picked up a used G11 with Gemini 1 level 4 version 1.05. When trying to align to a bright star the dec motor show's motor stall. I figured something must be binding, so I took out the motor and tried it again, same thing, eliminating possible worm binding. After restarting the system I noticed that after putting the mount? in sidereal rate the ra motor seems to spin at a that I would expect but the dec gear is spinning at a few hundred rpm not with enough torque to move the mount. Then when I try to align on the hand controller, it speeds up to a high rpm for a split second then shows the error. When turned off the motor turns by hand freely. The power supply that came with it is at 12v so I tried a higher voltage one at 14.5v, no different. Where do I start?

Thanks

John
