Orion Dual Axis drive problem. RA axis is moving in same direction on pressing both switches.

Hi friends,

I have a Orion EQ Mount with Orion Dual axis Motor Drive (Not of Go To kind) attached to that. After working nicely for last couple of years now it is showing a peculiar trouble. On RA axis, the drive runs in same direction on pressing either of the tow buttons in the hand controller. But the DEC axis buttons are working nicely .  A promotional picture of the same drive is attached with this post for reference.  Please help. Regards and thanks- Debasis

Could be anything form a broken switch to corrupted firmware.  The only way to narrow it down is to open it up and test the switches using a test meter.  The fact it's registering a button press on either button would suggest the switch is functional, but depending on how it is wired and how the input to the circuitry is made.  If the switches are wired such that each has its on input then this would suggest the firmware on any microcontroller is corrupted, if it uses one pin that goes high or low depending which button is pressed then it could be the switch or any pull up/down resistor that has blown.
