I have been finding that periodically the motor will stop tracking.  I can hear it stop.  If I touch the tube gently it will start up again.   Any suggestions or maintenance?   Scott

 If a light touch doesn't introduce mechanical vibration I suspect it's an electrical connection problem, perhaps at a board component level.

Check the electrical connections / wires from the circuit boards to the motors.

Could be many things but since it starts back up when you nudge it, check the solder joints at the motor under the black shrink tube.

As already been suggestion, it's possible it is a connection problem somewhere. If it has been sitting for long periods, contacts, plugs, etc can become oxidized preventing good solid connections. And if it was used a lot, it could have worn cable plugs and/or sockets for the handbox and DEC to fork cable..  It's also possible it needs a "lube job" since it is 24 yrs old.  Intermittent problem are always a bugger to figure out.  The easiest thing to do, with NO POWER connected, is plug/unplug cables to "scratch" new connections, including the ribbon cable from the front panel to the motherboard, and the plug for both the RA and DEC motors, as well as the cable to the fork arm.
