Thanks for these replies:
Problem appears to me that the stepper motors are not getting enough grunt so both your replies are relevant. The problem is intermittent since the mount will work fine and slew normally but then it suddenly stops. Maybe a loose connection etc but the electronic guts of the mount are a bit hard to get to.
I have electronics experience so how do you suggest I could go about checking the capacitors?
I will follow up your advice to closely look at the voltage/current supply.The 12 volt power supply stands at 12.65volts on no load then drops to about 12.3 volts when the mount is slewing in both directions. I should monitor this closely to see what happens to the voltage/current when the mount stalls. I can also substitute a known good power supply. Maybe (hopefully) as simple as a power supply problem.
