Adding Simple Sound to PW - 691ISND101/2 Boad Wiring Diagram

Wow - my first question to go cold and unanswered! Didn't it was that obscure!

Don't know the specs on the board, but you may want to pass the AC power from the track pick ups through a rectifier to DC first. Might also want a voltage regulator. I doubt the board can handle a wide variable voltage.

As far as the speakers, again you'd have to check the specs. Match the Ohms of the output to determine what speakers to use.

Jark, that's why I'm looking for the diagram/specs to figure out what it is I need...

Where did it come from? Can the seller supply the spec sheet?

I did a Google search with the part number you supplied, and I get referenced back to this forum. Zero results on eBay. Is the part number accurate?

Lionel (the supplier) has several boards in the ISND series, that have different sounds. Used mostly in the conventional classics series. These are horn/whistle and bell sounds. No chug or diesel motor sounds. These are stand alone boards.  The large square 2 pin socket in the lower right hands corner is for power input. ( Do not use a rectifier )The top 3 pin connector is for the speaker (only the 2 outside pins are used). The small 6 pin connector is for the volume pot, only 3 pins used. A on/off switch is also wired to this connector. Uses a standard 8 ohm speaker. 

For such a small board, it puts out a decent sound level.

Well, there you go!

Big thanks to the super amazing Chuck!

Any details on the 3 pins for the potentiometer and its range or which lines have the SPST switch?

The pot is a 10k pot, the middle pin is the wiper.  If the pot works backwards swap the outside leads.

GRJ,

I, too, was inspired to buy a couple of these boards this past weekend @50% off to add some sound to MPC-era diesels.  As I read through this thread to get the wiring scheme, it seems by your comment that the three-pin connector is the sound pot (since a six-pin connector doesn't have a middle pin) - while Chuck's note seems to imply that is used for the speaker + on/off.  Is that accurate?

Also, are there standard P/Ns for the harnesses?  They aren't listed on the parts breakdown I found for the associated F-3 on Lionel's web site.  Is there a "master list" of modern Lionel harnesses somewhere?  I saw this thread of yours which gives info on the power connector - so down to just the three- and six-wire ones.

As a side note: it appears that the speaker specified is 0.2W at 8 ohms.

I scoured the website and with my boards, ordered the following harnesses and such. I have not received them yet (or even a tracking number) so I don't know if I did right or not...

Of course, now I see I got a 5 POS for the POT, and not a 6 POS one... so I probably goofed there :-/

I whack my own connectors and wiring, so I don't have numbers for those.

Sounds reasonable. Any thoughts on the other question (i.e., whether the three- or six-wire connector is for the pot?

As stated above, the 3 pin connector is for the speaker, using the outside pins (middle is ignored). It isn't clear to me which pins on the 6 pin connector line up with the 3 pins on the POT and which connection is interrupted with the on/off switch. I think it would be easy enough to experiment with once I actually have received my parts.

If someone does know what the 6 pin connector type is or part number, that would be appreciated.

A clue to the ID of the pins is usually on the bottom of most of these boards.  I have four similar boards, three of them have the pins identified in the silkscreen on the back side.  The unidentified pins on the end of the boards on the right are the power and frame ground.

Unfortunately, the silk screening is pretty modest and unhelpful...

Order harness # 650-2471-013. This will give you the connector and wires. Let me know when you are ready to wire and I will check one of my Alcos and give you the specific order.

What about power and volume control?  You must need a little bit more.

John,

 The power in is correct, the other 3 pin is for the speaker. The volume control and the sound on/off is the six pin.

Odd, why did they call the harness above the Speaker/Serial?  Serial what, isn't this a conventional board?  In any case, you'll need a couple more connectors.   Looks like 2mm for the power and 1.5mm for the speaker.  Those can be had at Digikey, they're the JST PH and ZH connector families.

The harness is for the TMCC equipped Alcos. It is the only 6 pin mirco plug that I know of.  The serial wire and connector are not used. The conventional and TMCC Alcos are wired different.

I hate to disagree but the 3 connector plug is for the vol. pot.

OK, I should check mine, thanks for posting to correct my error.

That's what I thought, the harness was called the speaker harness.

Great diagram!  So, it there an on/off capability somewhere in the "speaker" connector / harness or does one just splice a switch into one of the other connectors?

You can always just use s SPDT toggle on the volume, one way is full volume, the other way would be no sound.
