I recently acquired an original 497 Coaling Station with the controller, roof, and bin attached. The wiring was brittle and cut off. I tried attaching a ground lead to the tab on the side of the motor and a power lead to the outside tab. The solenoid opens the chute just fine but it does not close on its own. I will clean it and it should work fine.
I then tried power to both of the inner lugs (separately) and the motor tries to turn but does not move in either direction. I opened the gear box and cleaned out old grease but got the same results upon a retest. Only minor movement on the motor shaft. The motor shaft can be rotated manually.
What do I need to do to get this operating properly? Am I missing something in the way I'm testing the motor?
Suggestions will be greatly appreciated.
