Re: GTO3600 runaway behavior

This is a CP4, so no split pin.

Steve, with some older mounts this problem was invariably related to the split pin in the power cord connection to the controller. If you pull the plug and gently spread the two haves with a flat bladed screwdriver, see if this helps. Worked for my AP900GTO CP2 long ago.

After running our mount for an hour or so, it will suddenly "take off" when given a slew or jog command.  Repeated commands via software to stop or abort don't work.  Pressing STOP on the keypad pauses the motion for a half-second or so, but the mount then continues.  The only way we've been able to stop it is to cut mount power.  After start up, the mount is completely lost and tracks at a non-sidereal (and significantly faster) rate.

This has happened for three nights in a row: the mount works fine for an hour or so and then goes rogue.

Any help, ideas, test, etc., would be greatly appreciated!
