This one took me about 5 hrs to complete.  I almost feel like a machinist more then a train repair electronic guy.  Though it was electrical that took about 3 hrs to work out.  Another tight fight that requires and upside down off centerline  placement.  Again clearances are close.  Thickness of a heat sink can cause it not to fit.  Otherwise went in nice with plenty of clearance for wires.

 

The issue was wiring.  Had to swap motor leads, Had to resolder all the smoke and volume wires that broke off.  Then I could not get the fwd coupler to fire.  Pulled this board out twice to put it in the tester thinking it wasn't working.  Resoldered all the pins and wiring for the light board at the coupler connection.  Had good continuity but could not get it to fire.  Many of the wires were too long so I did shorted them.  I finally got ****ed and direct soldered the PV and coupler wire to the coupler lead.  Worked.  Then I realized the PV wire was too thin.  So I direct routed the PV to the coupler and used a thicker jumper wire to the Light board.

 

I guess the PS-32 FET isn't firing long enough or the coupler is more sensitive to wiring gauge and length.  I have more than 20 PS-32 conversions under my belt and this was the first time I could not get function to work with the engine wiring.  Though I did notice that all the harness were extra long on this engine.

 

Anyway here are the pictures and glad to have this one done.  G

If this is a RK Turbine, been years since I did one, I think an upgrade kit with the 3V harness would allow the PS-32 to fit in the Tender. 

 

Some of these mid sized RK engines with boards in the engine are easier to convert with an upgrade kit and changing the 5V harnesses to 3V so you can put the board in the tender.

 

Right now, the PR Atlantic, B6, 0-4-0- and 0-6-0 type steam are the only ones I have had that can not fit a PS-32.  The board is too high or wide to fit the tender.  The only solution is a PS-2 3V or need to use spacers to raise the tender, which would not look very good in my opinion.  Also have some spare board brackets.  I already had one broken in shipping, and one shatter in my hands removing the board.  The plastic is harder.  Heard they are revising that bracket.   But don't take that to the bank.   G

George do you have the MTH  part numbers for the ps2 3 volt harness's? and are they going to be available in the future, as I do have many ps2 3volt boards since I was not to sure how the 32 boards would work out!

thanks George for any help you can supply for a MTH parts lit for the ps2 3volt conversion on my 6-8-6 steam engine and tender!

Barry is correct, the power handling is a major reason that O-scale boards are much larger than HO-scale boards.  A fairly large HO steamer might weigh two-three pounds, the scale Lionel Big Boy weighs in at around twenty pounds.  It takes a lot more muscle to move the greater mass.  O-scale freight cars correctly weighted come in around a pound, HO freight cars correctly weighted come in at less than half of that.

You can read the pinned post on PS-32 upgrade kits above.  PS-3 O/G is a larger board as Barry and John have stated.

 

PS-3 Steam and Diesels are totally different setups.  So for the PS-32 Steam upgrade kit you have a PS-32 set up meant to replicate a PS-2 3V type upgrade kit, just no battery, and a board that is slightly larger then PS-2 3V.

 

HO Is a totally different board.  G
