1  Discussion Boards / Large / Replacement Bulb for 38 Ton Shay Original version on: June 26, 2015, 12:54:56 PM
Does anyone know what I need for a light bulb to put in the ceiling of the cab of an original large scale 38 ton Shay?  I received this used engine and no bulb was in it.  I searched the parts store and no bulb was shown.

Bill, Just a quick follow-up to my wiring question for the 4-6-0.  The appropriate place to solder the red wire from the Bachmann "Sound" connection to the PCB is at the positive connection to the 9 volt battery.  When tested independent of the engine connection, it works fine.  Thank you again for the other reference material.

Thanks, I will review the schematics with my electrical engineer neighbor in hopes he can point out the right spot! 

Bachmann does provide the resistor with the LED lighting part so thanks for that input also.  I got that working.

I have installed Phoenix sound in all of my other Bachmann steam engines, but I was remodeling these two 4-6-0s to get them ready for two households of grand-kids so for now I think any noise is good.  Since some of the board mods in the material you referred me to are simple and not expensive, I may do those also.

Thanks again!

I had two old 4-6-0s given to me by a friend.  I tried my first "upgrade" by purchasing two new drive units as well as two new sound boards for the tender from Bachmann parts.  The drive units are obviously a great improvement compared to the old.  The SOUND labeled connector provided with the new PCB and the exploded drawing on the website showing the wiring for the tender shows the BLACK sound wire going to the volume rheostat (and there was an empty tab there that I soldered it to).  However the drawing shows the RED wire going to some vague location on the PCB.  Does anyone know where the RED wire is to be soldered?

As a point of information for anyone else doing this, I also noticed that the wiring according to the exploded wiring diagram for the 4-6-0 differs from how the drive units are actually wired.  The ON-OFF switch for the smoke unit on the new power units has only 4 of the 6 contacts wired, while the diagram shows all six being used.  I am also adding the LED light to the tender (the old one had no lighting) and this may be an issue for that, I am not there yet.
5  Discussion Boards / Large / 2-8-0 free wheeling drivers on: February 11, 2014, 02:08:19 AM
after putting my 2-8-0 on the shelf for a few months, i returned it to the tracks and to my surprise the engine drivers are "free-wheeling" so when power is applied the sound system works but engine does not move.  It can be pushed back and forth.  Any ideas as to what is going on?
