Hello,

First, this is my first PS3 diesel upgrade I have done. I upgraded my MTH Premier Conrail SD50 (20-2578-1) to PS3. I uploaded the sound file for that SD50 on MTH's website. Everything is working except the lights. When in forward direction, number boards are on and marker lights, front and back, are off. When I put it in reverse direction, the number board lights go off, the marker lights come on (front and rear), and the interior lights go off. Also, I cannot turn the interior lights off/on or the marker board lights off/on using the remote buttons.

I downloaded the sound file for this SD50, so is the chain file on MTHs website in that sound file for a PS2? Do I need to download a PS3 chain file in conjunction with the SD50 sound file? Again, everything else works as it should, and I have double/triple checked all my wiring per the wiring diagram. Any help will be greatly appreciated.

On another note, does anyone have any useful tips for getting the old marker lights out of the shell? They are definitely glued in tight, and it looks like my only option is to drill them out. Again, any tips/help will be greatly appreciated.

Why take the old marker lights out?  Just rewire them as needed and use them, they're already LED's and would be compatible with the diesel board.

If you are using the 50-1912 PS3 diesel upgrade kit you need to load BOTH the sound and chain file for a PS3 SD50 to get the lighting to function correctly. The sound file alone won't correct the lighting issue.

Thank you, I only downloaded the sound file. I found a SD50 PS 3.0 file, so I will download the files tonight.

I am happy to report that updating the PS3 chain/flash file fixed the lighting issues. Everything works advertised. A little snafu for my first PS3 upgrade, but overall it was not bad. Thanks for the help.

Bueno.

Going forward just remember that both the chain and sound files for the locomotive you are upgrading are required. The files loaded in the board out of the box are test files designed to make all the light outputs illuminate, so they can be tested for functionality.

Also note that if you're replacing a PS/2 board with the PS32 board, or doing a steam upgrade that uses the PS32 board, the process is different.  You do NOT use the factory PS/3 chain file, but rather one of the specific PS32 chain files for the PS32 board.  However, you can use either 3V PS/2 sound files or PS/3 sound files with the PS32 board.  Some PS/3 sound files may not function correctly, but many will.
