Thanks GGG, Just to clarify, here is where I am:
1) I put the loco on a small loop which is connected to the TIU and output #1. When I turn on the power to the TIU, the track sees 18-20 volts, signal strength is 10 (per another loco previously used to test) and the "J" sits there- dark- so I am assuming that means the engine is not suspect?
2 ) I don't have any way to recover the engine since I only have DCS wifi and it can't recognize the engine. Is there a way to do a recover engine operation?
thanks.
