Bought a used MTH 10000 set. Replaced the old battery in the engine with a BCR1 (older PS2). I'm having a hard time powering it up. When I move the engine by pushing it on the track, it does seems to make contact and power up normally with great sound and engine chatter. But then, in conventional mode, when I throttle down and then back up, it dies and will not start again unless I manually move the engine on the rails. I can't get it to go into forward or reverse. Any idea what is going on? It does the same thing in DCS command mode. Should I ask for a refund from the seller? Thanks for any tips or suggestions.
I assume the engine should work on its own without attaching the lighted cars.
