Good news. Engine is running now. Bad news I think there might be some trouble with the e unit. Train will only run in reverse 99% of the time. I believe the e unit is also buzzing a little bit louder than my other engines.
Also the few times I was able to get going forward it ran pretty slow. Not as fast as it does in reverse.
Also I've run the engine around with the housing off. I did notice some small blue sparks on the commutator/brushes. Is that normal? Not all the time, but enough to grab my attention.
Thanks!
