Response to questions that I couldn't get to yesterday: The mount is an LXD 650, "computer drive system, LX quartz - DC servo motor, smart drive." When it last worked properly both motors were running fine, then it suddenly began to slew wildly and hasn't worked properly since. I suspect, therefore, that the problem is in the electronics or "smart drive" system (whatever that is). Some of you may recall that Meade, being ever-so-contraire, built all their drives during that period to run on 18V DC rather than 12V DC. (Do they still do that?) I've tried powering it from both a 12V source and from house current with a Meade 18V transformer, but no difference. Meade actually sent a second hand controller some time back so I have two; neither works. The mount will power up and the hand controller light up but nothing will function. Again, I suspect internal electronics are the problem. Chuck, I'll get back to you off-list. I may want to sell or see if someone with the know-how can make it operable. At this point I don't care if I have go-to capability or not. Kim
