Can this PS2 conversion work?

The SD70 board will work if PS-2 3V, but the unit is meant to have a slave board for the other motors.  2 8 ohms in parallel will work with PS-2 3V board.

Below is a picture of a veranda which has walkways so less room.   G

Unless you really need four motors, one option is to remove two of them and do a normal diesel upgrade.

Why would you trash a perfectly good Premier loco, when it is simpler to buy an upgrade kit and slave   board?  or skip the slave and follow grj's advice.  You could probably sell the Premier for more than the price of an upgrade kit.

Sam, how are you going to power the smoke and lights, without a board?  You could obtain a Chinese CV board---AC/DC buck converter (they're cheap) and set the output voltage to whatever these units require, but would not have control over the on/off or volume functions.  You would also have to buy couplers.

From the requests for help on the forum from persons seeking to move the DCS electronics and on-board wiring, it would seem that getting an upgrade kit might be easier.  But it's your call, of course.

Do you have the 2 rail version??

RJR, you got it, I was going to use an AC to DC adjustable converter for the smoke unit/lites in the SD70 unit, move one of the couplers to the rear unit and control it from the head unit, use track power for the lites and smoke thru the regulator...BUT, I am considering your ideas too...

Joe, the Donner unit is a scale wheeled 20-2831-2. I got TWO of these units, different cab#'s a while ago for about $400 if I recall correctly, and I do not need two powered ones so my thinking was to get the Propane Turbine running (looks like a bad PS2 in it) and have the other SD70-2 units MU'ed up (is there such a word; MU'ed up ). I want to keep the cost to a minimum...

John, I like to keep the four motors in the Turbine if at all possible, but it sounds like a slave board is needed because the standard PS2 board can't drive four motors...

I have not decided on the final plan yet, that is what this board is all about, get  ideas/opinions....

Sam, many years ago I upgraded a Williams Shark A-A unit to PS2.  I used a subminiature plug socket to feed ground, coupler, and light to 2nd unit.  The units had a rigid non-operating coupler.

Another alternative worthy of consideration is to contact GGG, who is the acknowledged board repair expert, and discuss whether he could check the main and slave boards or possibly repair them.  Postage for the boards is cheap, compared to the cost of what you're considering.

RJR is correct.  What doesn't work?  This is a PS-2 5V with slave, so you really are looking at board replacement only.  You probably have to do some modifications to mounting if you go with a PS-2 3V board, or find a doner 5V engine.

Need to make sure slave board works even if 5V board is dead.  G

 What a deal you got. I search high and low for the two rail versions most of the time. There's plenty of the three rail ones but usually not the scale wheeled fixed pilots. They are usually spoken for.

Yes.  G

I believe you still have to be an ASC to buy the slave boards, the slave kit part number is ii-0001950.

Thx Joe. I got them because they were less than $400 for both shipped. I have bought many enignes just because they were a "good deal" . I usually do not do FEC RR but they look good and my plan was to use the PS2 from one of them to upgrade another non powered loco... May be I should sell them as is, make some money and then purchase a steamer!!! What ya think?

I don't know if you use KD's or like the fixed pilots?

If not, let me know. I too have bought many engines because of the deal. The problem now is there are too many. Sometimes the conversion to two rail, leaves them backed up in storage. That pile is forever growing!

 I do have a RK B&M mountain steamer looks new in box, if you're interested, we could do a deal. I also have some diesels.

 Most of my other steamers, are two rail, or have been converted. I mainly hunt for modern diesels.

Hi engineer Joe how much are you selling you steam engine for, or what are YOU INTERESTED IN TRADING for the engine?

Alan

do you have any pictures of the steamer?

 I bought it for the grandkids whose interest keeps changing. All of a sudden he was after Amtrak, which I got here on the forum.

I'm always after any two rail engines that I don't have.

PS-2 3V and 5V slave boards are the same.  AC-0000011.  PS-3 is not, it is totally different as PS-3 slave units have tachs.

The slave upgrade kit for a Turbine is ii-0001903 and for F-x ABA is ii-0001905.  But as John states they are sold to ASC only because of the extra complexity of the install.  G

I prefer fixed pilots of course and 2R track too, but I like so many locos the selection in 3R meets my needs so I am stuck with center rail and moving pilots which I certainly dislike a lot.

I do have a few MTH 2R steamers and Diesels, Like them all...Plz email me and we can talk...Cheers!

John and George, Thx again. I am rethinking my plan. I am also going to deeply check the Turbine problem....Will report findings as they happen.
