Ok, so I have tried all that I know before reaching out and I'm out of ideas. I've got an MTH sd70m ps-2 model 20-2612 from 2005. I recently purchased it from the bay so I don't have anyhistory. The engine will only run in conv mode. When I try to add it all I get is no enginefound. I've just finished updating the much older firmware on the TIU & remote to the latest (4.2) to see if that would fix it, unfortunately it had no effect. I've left the engine on a powered track long enough to charge the battery, plus the sounds are fine in conv. I can add other ps-2 locos just fine. I've tried to do several factory resets with conv and it took because I got the two horn beeps, but that didn't fix it either. When I apply power to the track with DCS, I do here the engine click as if something is going on. The strange twist is that when I first put the engine on the DCS track it did load for me once, but when I disconnected power from the TIU, I couldn't get it to work again, DCS was telling me "engine not on track". I'm still new to DCS, but not to HO DCC. One question I have is are the engines supposed to stay in memory when power is removed from the TIU? Also, is there any way to stop power to the track without removing power from the TIU? Is there any way to do a factory reset with the DCS remote without the engine being found? I don't have an authorized MTH service center anywhere near me, so I can't take it anywhere to get checked. Any ideas?
Thanks
