This is the RK SD90mac PS 2 from a while ago. I tried replacing the BCR with a 9v battery to see if the system could read the engine. I get lots of errors like "Check Track",
"Engine not on track" and then suddenly "Engine found!" but it loads as a TROLLEY.
I get all PS 2 features except those that would be under "more..." like FYS, couplers, bell, horn, crew talk. Under the hood looks fine. It hasn't been that long since I ran this loco so I don't know what changed. My other PS 2s work fine using my test track. Only this one seems messed up. Maybe solar flare activity this year scrambled the board inside?
