Reply to "Help repairing a K-line with TMCC- sounds but no movment"

We just gad this discussion a couple of days ago.
GRJ noted that that was a typo on his part.

Code 78 is sometimes the code for Diesel with cruise and smoke. Otherwise it is 8.
The reason I say sometimes is because my 4-6-6t with cruise and fan driven smoke uses code 74 per the K-line manual

My K-line scale Berkshire with cruise and puffer smoke uses code 4 per the manual.
My K-line Pa-1 without smoke or cruise uses code 8.

I would try code 78 first than code 8
Code 74 is for Steam
