Y6B 20-3009-1 PS1 to PS3 Upgrade "Issues"

So, I believe the discoloration on the PWB is not a "burn", but rather liquid from the capacitor that leaked out and discolored the board/connector.  When moving 12 years ago, the engine was in storage for probably 8 months, so it wasn't flat.

I decided I am going to have the headlight DCS controlled, but do I need to swap out the light and the wiring?  I'd rather leave the old bulb and wiring in and just connect the new PS32 wiring to the old bulb wiring.

Still looking for the best MTH PS2 or PS3 smoke unit part number.

Yes you can use the old bulb.  I have this engine.  All bulbs in engine are 6V off CV board.  Not sure what that is, does the CV board still work?

You need a AA-0000029 PS-2 smoke unit.  You will have to make a bigger stack.   I found a piece of flat aluminum would lock the smoke unit in place.  G

GGG - excellent.  Thanks.  The CV board still worked this morning.  Dave

Here are some pictures,  The flat aluminum plate winds up being a friction fit to hold the smoke unit up.  The PS-2 version of this engine uses a mount with screw into the bottom flat, but I did not want to drill the shell.  Mine is still PS-1, with PS-1 smoke.   G

George - Thanks!  I've got the AA-0000029 PS2 smoke unit on order.  Finished the PS3 upgrade, dressed the wires.  Everything works (except the smoke.)

I found a 4MB Y3 PS3 sound file that I thought was better than the 1MB Y6b PS2 version, and installed that.

When you said "Make a bigger stack," above, what exactly did that mean?  I was assuming I would need to open up the diameter of the existing stack on the boiler casting, but like you, I didn't want to mess with anything on the casting.  But looking at your photo, looks like you didn't do anything to the boiler stack.   Without the AA-0000029 in hand, I now think your comment means I need to adapt the OD of the PS2 smoke unit stack to match the ID of the boiler stack.  Are there "custom" stack adapters available, or did you turn your own?

The brass cup on the MTH smoke unit is a small diameter and will not fill the engine stack.  I took brass tube from hobby shop or do it your self center that had an outside diameter to fit the engine stack.  May have been 3/8"  you can measure the unit you took out.  The inside dia almost fits over the smoke unit brass cup.  What I did was use a pipe fitting tool to widen the end of the tube, to get it started over the cup, then press on with vise.

It can't be too long other wise you can't fit the smoke unit in.  So this takes some measurements.  Basically works to help hold smoke unit in the stack and makes sure adding smoke fluid goes into the smoke unit.   G

George - thanks.  OD of the Seuthe is right around 3/8" (not calipered - visual on a tape measure).  Off to the store to get some brass tube and a pipe fitting tool, but can't go much further until I have the smoke unit.

For anyone else following along, here are some steps I did so far.

#1 - took off the cab. Probably could have gotten around this step, but it made it easier to do step 2.

#2 - took a long dowel and tapped the front of the boiler off from the inside.  It was definite tight fit and needed the dowel and some taps on the hammer around the edge to press it out (there is a screw to remove, too, on the bottom).

Inside of boiler:

Fabricated a small foam stock piece to test fit.  Need to convert this to aluminum.  But exact size, placement and screw holes will need to wait until my new PS2.0 smoke unit comes next week.

Your going to want to notch out the rectangular shape of the boiler cover.  So it can fit back on.  You can see the cutout in my picture.   G
