Hi Andrew,
I haven't fired up the motors for a while, but this is what I posted on the LXD75 Yahoo group:
Standard Controller:
RA Motor
•Performs initial test when a direction button is pressed
•Slews both directions, at all four speeds
•Appears to function normally
DEC Motor
•Does not perform initial test
•Does not function at all when direction buttons pressed, at any speed.
Autostar #497 43Eg
RA Motor
•Left button does not slew, or is very slow to react.
•Right button does not initially function or functions intermittently; very
sudden stop/jerky when button is released on max slew speed
•Sometimes slews by itself after turning it on, stopping randomly or not at all until I switch the mount off.
•The RA coordinate displayed on screen does not change when slewed. Only changes by 0.1' which I assume it thinks it's turning at the sidereal rate.
DEC Motor
•Does not function at all, at any slew speed or direction
Other notes:
•Calibrate Motor option activates the RA motor, but not the DEC motor. No motor fault given.
•Neither motor starts when attempting to slew to an object selected in the menu.
•Occassionally the DEC motor springs to life and functions almost normally.
•All cable contacts cleaned (DEC to RA, HBX (both ends)).
•Swapping the Autostar cable end for end does not make any difference.
•Autostar has been reset and firmware reloaded.
•240v to 12v 2.5A power supply used.
I've tried two controllers, the standard D-pad style that came with it and a Autostar 497. Plus I've done the usual things like cleaned all cable contacts and tested each wire with a multimeter from board to board (ie contacts on the boards where the female connectors are attached), and different batteries/power supplies. Fairly sure the DEC motor itself works if I unplug it and plug it into the RA board, so the motor itself is ok.
Any help would be greatly appreciated.
