MTH proto 2 premier gg1 pantographs not working

Motor can go bad, but do either move they are separate?  If not I might suspect a wire harness or board issue.  G

Is there a switch to turn them off under the loco?  Is the battery fully charged?  A Factory reset won't take on a dead battery.  6 screws and the shell can come off and you will see the harness.  If it worked before you stored it and doesn't function now, I would look at the simple things first.  G

Glenn,

Are you certain that the pans aren't pushed down into the locked  position?

Try lifting them manually a bit. If they don't move at all, firmly but gently snap them out of the locked position.

If this is a PS-2 5V board with the 8.4V battery, I would go with a new one if it has sat for a few years.  I could not remember but I thought there was also an on and off function for the pantograph besides the power or pickup switch.  G

Trace wires to the 2 aux board that drive the pants.  Make sure all wires connected no loose 10 pin connector.  Unplug motors and try to run with 9V battery short burst.  Look at the 2 aux boards for damage.  At this point, it becomes swapping boards to determine what is wrong.  G
