Hi have a problem with my eng was not working ,found it has 3 wires going to a sound adjusting pot red blue yellow, and they hook up to a pcb with a number 691-RSOE-A00 on it
tried to look it up on the lionel website got no hits. can anyone out there help me. i'm thinking the number on the board is not a production number just a board no.
if anyone could give me a clue i would appreciate very much
i can send or post a picture if it would help
