Reply to "Chuff and sound issue"

Thank you for the replys. 

I did disconnect/reconnect connections in the tender but nothing helped. I didn't want to open engine if not needed. 

John, I didn't see a switch in lionel parts break down. but if the smoke unit pulses correctly should that relate to the pulse signal for chuff is present or working. I assume it is the same electrical signal used for chuff and smoke?

Thank you
