I stuffed some PS3 guts from a cheap RTR 2-8-0 into a nice premier 2-8-0 recently.
The RTR loco didn't have an interior light, firebox light, or marker lights. I installed those in the new engine and connected them to the appropriate outputs. I loaded a good Premier sound file into the engine, and flashed the appropriate chain file (in that order).
Everything seems to work great, with one small exception. When the engine first sees power, everything powers up as expected (before pressing 'startup' on the remote). Markers, headlight, smoke, firebox glows with a flicker, and interior light illuminated.
But as soon as I press 'startup', the firebox switches off and cannot be toggled back on at all, even though the remote says it is. All other lights behave as the remote commands, and I can toggle the markers, headlight and interior light on and off using the appropriate soft key on the remote. But not the firebox. The soft key is present, and shows cycling on and off when the button is pressed, but no reaction in the loco.
If I cycle power, the firebox comes back on and flickers away until I press 'startup' again and it disappears.
Do I need to reload the chain file? There were a couple errors during loading where the loader software said 'retrying at a slower bit rate' and then seemed to be successful and moved on to the next sector. But other than that I saw no other errors after flashing the chain file.
The loco board was not the relay version board, and I think I selected the right chain file for the non-relay version of the loco board.
Thanks
