I'm trying to fix a friend's Skyprodigy mount. He's not used it for a year or so and, while the azimuth motor works, there is no movement in the altitude. I've swapped over the connectors for the motors at the control board and the azimuth continues to work (now using the up/down buttons) but still no movement in the altitude; so I feel reasonably confident it's a problem with the altitude motor and not the control board.
However, I cannot see how to disassemble the mount to access this motor. I've removed the base and the screw by the power connector as well as the main nut on the spindle, but this doesn't seem to help. I can see there are a number of screws with Allen key heads behind a couple of plates but am reluctant to try them as I'm not sure if they are only for allignment. Additionally I'm uclear if I need to disassemble the camera first, and if so how.
I've found Mike Swanson's notes and photos but these do not seem to match this model with the StarSense Camera.
Any hints or tips would be gratefully accepted before I dive in further.
