Just completed another ERR install. This is about the 8th one I've done. It was a Proto-one-echtomoy of an MTH C&NW #4008. It is running however, I am losing chuff occasionally for what seems to be no reason and this loco is having issues at most of the gargraves/ ross switches. On the power loss at switches, since none of the other locos are having this issue, I will assume that it is a rails/ pickup issue with this specific loco? I cleaned the rollers with no improvement. They are slightly worn but I have seen much worse with no issue. Would replacing the rollers be in order here? I am also considering adding aan additional pick up on the tender since I have over 30 switches and things like double crossovers and such. What else could this be and does anyone have a source for pick up rollers (checked MTH site but it just kept coming up with no stock that I could see)?
On the loss of chuff, I literally thought that the magnet was coming off. But it does not. If I stop the loco and back up, the chuff returns. It seems like there is a lot of play in the tender wheel. Could the wheel move far enough away from the reed switch that is loses "contact". I placed a nylon washer on the axel to tack up some space but it still seems to happen. Any thoughts?
Any suggestions on these issue is appreciated.
