Reply to "MTH 20-3029-1, converted to PS2, no sound/smoke"

For conventional operation you need the volume pot and the switch to control the functions.  Without the parts you can arrange the wiring so that the volume is always full-on (or full-off) and the smoke always ON (or OFF)...in other words no control but the functionality is there.

Take a look at the PS2 Steam upgrade manual.   Some relevant pics copied here:

12-pin harness

There is a 12-pin connector on the electronics board with wires that go to the volume pot and smoke switch.  Since the kit comes with these wires, it's hard to imagine why they would have been removed.  I understand them not being connected (if conventional mode was not needed) but I'd think they might be there.

The parts list for the 20-3029-1 shows the volume pot and a switch in the tender with cut-outs on the bottom to access the controls.  The volume pot (item 19) has a unique plastic holder (item 20) which aligns with the mounting holes.  It's curious someone would remove these parts; sure, leave them disconnected if not needed but why remove them!

original parts

If for whatever reason these parts are indeed AWOL, the parts list gives the MTH item numbers down to the last screw, washer, etc.  I suppose you could use a generic volume pot of the right value and a random on/off switch...but the cutouts on the floor of the tender exactly fit the MTH parts simplifying installation/mounting.

Not having the wires hooked up for conventional control of the sound/smoke unit was the issue. Thanks! The wires were tied off to the side in the tender. I temporarily hooked the wires together and everything works fine. I'll be buying the volume pot and smoke unit switch from MTH shortly.
