I had a nightmare with the MTH George Bush loco. I could get it to program on my club’s NCE, but as soon as it lost power (even picking a turnout), it would reset to factory defaults. I am also swearing off their stuff now unless it’s a locomotive I can’t find with another manufacturer and am willing to add the cost of installing a better decoder on.
if mine does that (Its been a few days since I last ran it)then I think I will just leave it.
Supposedly if they lose settings this indicates a fault that can eb repaired. MTH uses a supercapacitor or a battery (seems like maybe the battery is in the larger scale locos, supercap in HO ones) to retain the configuration, instead of just using non-volatile memory like every DCC decoder (once again, one has to wonder what the designers at MTH were thinking), so if this fails, the settings are lost. If your loco is losing settings like this, it probably should be sent in for repair.

Would a supercap be able to hold volitile memory for any length of time beyond a few seconds or minutes?
Yes, the NVM draws nanoamps, a supercap can keep that foor years. Most computers no longer have a battery for the RTC and BIOS settings - they use supercaps. Have for some time now.

Well good to know thanks.
I ran #5642 The MTH locomotive last night all the settings were there just as configured last week.
