I have a new Challenger #1931260 #3985 that I got back from Lionel and because of medical problems just got out to test. I have 2 problems:
1. No dyno smoke - I feel warm air out of the Dyno but no smoke - I used 20 drops of Lionel smoke fluid
2. Noise about 1/3 from front of engine similar to smoke fan, 3-1-3-1 sequence continuous short noises. NO change with both smoke unites on or off, engine reset, moving or stopped.
Any ideas what I can do other then sending it back to Lionel? Thanks Bruce
