SSPRR Run Room

Playing with Toy Trains

MTH Mel's Drive-In Diner (#30-9105)

ssprr_run_room042001.jpgThis accessory was purchased in 2001, and installed in May of 2008.

After installing the Diner, the sound was bad. When the sequence started, the sound acted like a 78 rpm record played at 45 rpm or slower speed.

I purchased a new motor from MTH. That didn't help. The fix turned out to be resoldering cold solder joints in the main circuit board in the tower. Below is a summary of the repairs.

To remove roofs, carefully remove the plugs to access the screws.

The main circuit board in the center structure is the one that had the cold solder joints.
Use colored markers to code the connectors before removing connectors.
Remove connectors with care.

The open bottom contains the gear train that shouldn't need servicing.
