Yesterday, I ran my Frisco ten-wheeler for, oh, say 20 minutes, and all was well.
Today, it is behaving very erratically. When I power up the track, the cab, firebox, and class lights burn steady, but the headlight flickers rapidly at time but burns steady at others. It does not respond to commands in a consistent manner. It will move a bit and then stop, move and then stop. It might run very fast for a few feet and then crawl. It might just move a fraction of an inch and then stop. Sometimes, continuing to turn the wheel on the remote will make it lurch along, sometimes not. The bell might ring when the button is pressed but the whistle won't. Or neither will work. Most of the time is simply ignores me.
I have verified that the pick ups are clean.
The ten-wheeler is on Track 2: the remote is working fine controlling an engine on Track 1.
Another TMCC engine runs fine on Track 2 with no other changes (which I think pinpoints the problem as being on the engine).
I have reset the engine and also readdressed it.
I would appreciate any leads on trouble-shooting.
