Hello, first time post. Just unpacked my Marklin stock after 40 years in storage. I have been adding stuff and got a turntable from Ebay. Problem is the motor doesn't stop before it jam the alignment cog. So now the relay that is supposed to pull the track alignment cog out to allow rotation cannot overcome the jam. The brass gear actually climbs up the next ridgen in doing so. I see no adjustment for this problem. All linkages move freely and nothing seems bent or missing parts.
