Had some time today to spend on the layout and was running a MTH Big Boy 20-3127-1. Since new this engine would occasionally experience a problem with stalling and stopping, usually right after changing directions from forward to reverse. I have not run this engine in a couple of years so I thought I would put some time on it and see if the problem still existed. After about 15mins trouble free run time it finally acted up and sure enough it stopped dead. After some extensive checking, I'm fairly certain I have it narrowed down to a problem in the tether, and/or a tether connection. In the process of doing the trouble shooting I had to do a few feature resets. Immediately after selecting this engine to do the reset on I would get the display shown below. I have never seen this before, but it consistently happened several times. Any idea what it is?
