Is your Gemini 2 one of the old ¡°long boys¡± or the current, square Gemini 2. The older ¡°long boys¡± occasionally suffer from a broken solder joint that can cause an RA failure message. It¡¯s a simple fix but does require some soldering. Try Brian¡¯s suggestions first and if still no joy contact Tonya at Losmandy (better to call in the afternoon) and she can walk through some additional steps. I had a similar issue a few months ago and ended up sending my Gemini 2 box in for repair as I¡¯m not comfortable soldering electronics. Total cost including shipping was about $100.
Best,

Hi,
Since a week I have a big problem on the g11 gemini2 of mu observatory.
This is the third time I found the mount complexity stopped.
Seems both motors stopped working during the night.
After that almost impossible to move any axes, even after power cycle.
I have the message RA/dec lag message.
I passed the whole Sunday in the observatory trying to find find the failing component
Swapping cable with old ones : work better. (Move a little between fails)
Swapping motor no change
Removing motor no change
Unplug ra motor : dec works normally
Unplug dec motor no change
At the end I was able to retrieve a fully functional mount after swapping the optical encoder of the ra motor with the one of an old legacy svm motor
¡ but only for 2 days.
This night complete failure again.
Even worst. No move at all. Try ten of power cycle. Even reformat of scared
I had to phone someone to move the telescope to be able to close the observatory.
I believe the problem is on the gemini computer itself.
Given the symptom do you believe a repair is possible ?
Does it seems like a known failure `?
Thanks
Erwan
