Received this engine for Christmas. After some tune up and a BCR addition all was running great until today. Went to fire up the layout this morning and this engine shows "inactive" on my IPhone (running DCS with Wifi). Repeated attempts read the engine gave the same result. Shut everything down and tried again - same result. All my other MTH engines are recognized as "active" and run fine.
Suggestions appreciated. Could this be a victim of the older PS2 5V board failing?
