PS2 steam upgrades

Hump Yard MikeHump Yard MikeOGR Forum Member SUPPORTING MEMBER

With the Steam PS2 upgrades I have done, I have been using the constant voltage board for the cab light and marker lights, and then using the headlight output from the PS2 upgrade.

 

I have a sick MTH premier big boy .  It was working fine with some intermittent issues with the tether, but now will no longer function, I assuming a short somewhere in the wiring has wrecked the boards.  It has a factory installed PS2 where there is a need for lighted number boards, and marker lights, cab light and fire.  I am looking for a game plan to repair this myself with an upgrade kit. 

 

Assuming the board (mux?)in the boiler is bad that the smoke, marker, cab and number boards are powered from, what else could I use if I planed to gut this engine and start over with an upgrade kit?

Would the PS2 board in the tender be replaceable by Steam PS2 upgrade kit, I noticed the current one has two outputs, one for a back up light and one that is for the red light (bulb) on tender.

What is the board for the tach reader in tender separate from the PS2 board (looks like there might be opto's on this board).  Why does the steam upgrade kit not utilize this board?

If you want you can send me the PS-2 boards and I can test and repair the boards at the component level.

 

As far as the MUX board in the tender which is the transmit board and the MUX board in the engine which is receiver board....they rarely go bad.

 

So once you figure out your wiring issue and repair or replace your PS-2 boards the sound file will work with the MUX board and you will be back to original configuration.

 

As far as trying to replace if in fact everything is dead (highly unlikely) you can tap right into the PS-2 board for all the tender needs.

 

The issue is the engine, and you would be best with a CV board added like PS-1 and light up the equivalents.  You won't have DCS control of them.  I have also seen a cheap mans configuration to light the markers via the 5V but you will probably have a slight flicker that can not be eliminated. 

 

In summary, you just replace your bad board with the PS-2 upgrade board with the original sound file loaded.  Fix the wiring that caused the original issues, or what ever the cause was and your back to original. 

 

Are you sure the board is bad, and it just doesn't need the tether replaced?  I have replacement tethers in stock.   G
