Christmas Special O gauge Williams by Bachman set....whistle not working

[jjpdoyle]

I just purchased  the  subject set  with 4-6-0 locomotive. The digital true blast II  whistle worked intermittantly but now not at all. The bell works fine. How do I troubleshoot this ?

Dear  jjpdoyle,

Swap the wires (center rail wire to the outer rails, outer rails wire to the center rail) at the terminal track. 

Report any differences with the whistle and bell. 

Sincerely,

Joe Satnik
