Our MTH NP switcher, #1170, works great.
What happens is when I turn off the layout ... it disappears ....
Not in the inactive or active lists ... just gone.
So I do an ADD MTH ENGINE and it finds it and adds it and all is fine until I turn the layout off again.
Then repeat above ...
It's the only locomotive on the layout experiencing this dropping.
Battery is totally charged up.
Wierd.
Suggestions?
