I have a 6208065001 NYC 4-6-6 Hudson W/Railsounds #5412 that I purchase used a number of years ago. The other day I ran the unit in Command Mode for the first time and the engine performed well but it was missing a number of features.
I had head light, boiler light, smoke, direction, decent slow movement and Railsounds crew/tower talk with idle steam sound. What I didn't have was variable chuff, whistle, bell, reverse reset sound, backup light or rear coupler.
I replaced the R2LC with a 691R2LCC08 R2LC / RADIO RECEIVER (C08 CODE) board from Lionel, set reset codes but to no avail. It seems a though no serial data is being received by the tender.
Before I go further down the rabbit hole on this one and start replacing the DCDR and engine Motherboard can someone point me in the right direction? Any help will be greatly appreciated!
