I have recently ventured outside of pre and post war Lionel when I acquired an 8206 locomotive and tender with electronic sound steam and whistle. The steam sound works fine so I know the circuit board is getting power and the speaker works. I can't get the whistle to work. I have tried with brand new 8251-50 and 6-5906 controllers. The wirnig diagram showing how to wire the controller into the circuit leaves lots to be desired. Where might I find a more detailed WD? Also if the whistle control portion of the circuit board is shot, can new circuit boards be purchased? If so, anyone know where?
Any help I can get will be greatly appreciated.
