I just bought and received this Meade 2080 LX-5 and a small (maybe) problem in the set up routines.  I applied power this morning to check out the Dec motor and other drive motors and I get no response from the Latitude ?? right/left  or E & West buttons on the remote handset.. I feel there is no power to the motor or...the motor has died.  Where do I find this motor in the base of the fork?? And repair suggestions if any and pointers on where to look.   My thoughts tonight are to pull the front cover and see if any loose wiring has occurred in shipment.  The prior owner said in e.mail that it was working when he tested it a few weeks ago..  Thanks.

PS.. its a very clean and nice unit..

Are you sure the motor isn’t running? The LX5 RA motor is very quiet and if you aren’t looking at the stars the scope doesn’t move noticeably with the hand controller or without. Try pointing it straight up and leaving it for an hour or two to see if it moves.

The LX5 is not a Go-To telescope. The motors will not slew fast at all. It is intended for making guiding corrections when taking astro photos, or for centering objects visually already in the field of view.  The RA (Right Ascension) motor is very quiet but you should be able to hear it in a quiet room with your ear close to the base. Take it outside and point it to a bright object. In daylight look for a reflection a ways away. Center it in the eyepiece, preferably a high power one, or better yet a cross hair eyepiece. Then with it powered on, look through the eyepiece. You should see very slow movement to the right (objects appear to go left). Then press the West button, the movement should increase a little. The East button just stops the motor for the object to "catch up".

Thank you so much Gentlemen and I do mean gentlemen.. This answers my question sufficiently.  Getting me feet wet for the first time in astrology.  Mystery to me is just where is this motor that drives this scope??  It has two speeds... I love the scope for its simplicity.  Thanks again and God Bless you all, like it or not. :-)

There is a metal cover on the bottom of the base. If you remove the 4 screws you have access to the RA motor and worm. Mine did not have a dec motor but I believe they were an external motor that attached to the dec knob on the fork

Problem has been solved  .. there was NO problem to begin with... My problem was with my Cochlear ear implant and my implant batteries were on the low end.  New batteries there and I can hear the motor fine.  Also did the E and W Tracking with power on and it tracks both ways nicely.. Thanks for all the assistance.

Its a learning process me thinks... Cheers....
