You did Train the drives and CALIBRATED motors using the same power source you will use outside?
Do not run off of the internal batteries UNLESS they are brand new. Once the batteries drop below about 70% the hand controller goes a little crazy. That's why most people use an external power pack.
1. Replace the batteries, and do a Calibrate motors.

This is usually caused by low battery power-- as the hand controller reported. DO NOT USE rechargeable batteries they do not have enough volts. Use alkaline batteries only.
This can also be caused by a broken gear or a failed internal motor. You can return these to Meade for repair.

Is this a 497 hand controller? If it is check the TELESCOPE TYPE in the controller. It should read ETX125. You cannot just switch controllers. The controller has been TRAINED for the other scope.
To switch it you must do a RESET, Calibrate motors and then train the drives. These "values" are stored inside the hand controller. If you move it to another type of Meade telescope you must RESET and do Calibrate sensors and Training again.
The dis-assembly pictures are located on the Mighty ETX web site here: http://www.weasner.com/etx/menu.html
The ETX125 is notorious for bad motor control. Weasner's Mighty ETX web site has links to repair centers that are more reasonable than Meade. They also have a QA section to assist with diagnostics.
The manuals are all available to download from www.meade.com.
If your scope has the motor drives and a control panel into which a controller could be plugged, then you just need to buy an Autostar 497 - always available on eBay for about £85. However, there are older models of the ETX which only have one motor or as a spotting scope for terrrestrial use with no motors - Autostar cannot be connected to these.
Look at the pictures of scopes on eBay which come with Autostar - if your looks like these, Autostar will fit. Else you are out of luck!
Hi
In response to your email the whole unit is being returned to supplier motor problem is manufacturers electrical fault the meade etx-125pe should have motor limiters fitted which stops the scope slewing more than two revolutions in any direction to stop potential wiring damage this unit does not have them or they are faulty hence motor fault.
