I have an MTH 20-3089-1 Union Pacific Challenger with 5-Volt PS2 bought new in 2002 that I am preparing for one of my grandsons. It has been in a display case and has not been run until now.
I removed the MTH white battery and replaced it with a BCR. The engine runs properly in forward and reverse but I don't hear any chuffing. The horn and whistle sound volumes are very low and almost inaudible. I also tested it without the BCR but the symptoms are the same. Two wires are connected to the speaker and two to the volume potentiometer. Solder joints look OK.
I've read this thread and it seems the speaker is the likely problem. The speaker in my tender is Star NR-05009-01
- 16 Ohms - 5 Watts - 231E - 50 mm diameter across the 4 mounting tabs. (see photos). MTH parts shows it out of stock. So - two questions:
1) Is the speaker the likely problem?
2) Where can I acquire a replacement and what brand should I buy?
Thanks for the help.
