Moved the jumpers as you requested and the machine went into slow motion.  I moved them back to the left side, which is where the instructions said they should be for the Meteor.  I have considered the cables as a possibility, but I've taken them out of the backbox and tested them on the bench and have continuity from one end to the other in the connectors so I don't think that they're causing the issue, but I've been wrong before.  Any other ideas?
