Dave, this is a cheapie model. No numeric keypad, just three buttons. One corresponds to "east", one to "west", and the middle one says "speed" on it. I opened the hand unit up and the "speed" button is actually a DPDT rocker-style switch. Anyway, the upshot is that there is no computer. Just resisters and LED's. I have thought about reversing the polarity on the heavy-duty battery pack, but if I did, then the LED pilot light certainly wouldn't light up. Maybe that would need to be reversed and re-soldered as well. I doubt that Meade ever even sets a hand on these cheapies unless returned for service. They are made in China. Total junk. Even the polar axis bushings have so much slop that it is pretty much useless for anything other than the lowest powers. On Dec 12, 2007 7:06 AM, Dunn, David <David.Dunn@supervalu.com> wrote:
Chuck,
I am also perplexed by the fact that it runs fine with the 9v but backwards when it is removed. I saw several examples yesterday that indicated that Meade had mis-wired some of the controllers and that you had to enter a negative number in the setup to get them to go in the correct direction. Maybe the battery pack is wired wrong. Do you have a model number for the controller or telescope? I saw the issue mentioned with Magellan I and some Astroscans.

Most modern Meade scopes that I've seen have a user-selectable switch for N/S hemisphere use, whereas this particular drive has none. It was purchased right here in the USA some years ago, I'm told. I have the original box and the shipping label is still on it.
Also, why would it operate correctly with the 9v battery in the hand paddle, but then run backwards when the 9v battery is removed, and the auxilliary battery pack is plugged-into the motor case?
The bigger question is, Why do these 'scopes from hell' seem to find me? ;o)

Welcome back,
Per chance could it be a scope that was intended for use in the southern hemisphere?
