I cannot get any of the links to work....

If you want you can email me, or I can add folder to my dropbox and invite you to mine... then I will post them on my site and reference the links.

The links you show seem to imply that they are from your mail system, and only you can see them.

Got 2 pictures, but one of the display table, and the other does not show the tender, the only thing changed...

alright Ted! You were whining almost every day about a picture, now you are at the Convention, where is YOUR picture?

Yes, please use RCS of new england.... nercs threw me too!

They have used that name for some time... and TOC is still under that name to a degree in Washington.

Greg

hah, I thought all the docs were the 1st gen, but looks like they are all 2nd gen.

So lucky!

Thanks again, Greg

update: loco fixed, the small contacts in the truck did not properly engage the contacts in the swivel plate.... just bending the 4 contacts out so they better contacted fixed it.... maybe it ran at the factory, but this is the first time it has been run since purchase some years ago.

Greg

Was adding a decoder to a new in the box 2nd gen Climax.

No movement from front truck, rear truck fine. Power pickup on all wheels front and rear.

Anyone know how to remove the truck, pulled the bottom plate, and there is a small board and then the motor right in the middle of course.

Greg

Need to mention the 7th generation now, with the updated tender and electronics...

To attach images (that can be referenced by a URL,  you cannot upload them) see the icons in the editor menu, bottom row, 2nd from the left.

So, did this answer your questions? Bachmann documentation is sort of weird, I would like to see a schematic as an engineer, but you get a "wiring diagram" and often stuff is left out.

Greg

Well, you asked about 4 switches, so I wonder where you got that idea.

So, on the link provided to you:

First page shows the 2 switches behind the smokebox door. One is the "NMRA vs LGB" track polarity switch, and the other is the smoke on off switch. Note the circuit board the switches are on: G821X-PCB04

Now look at pages 13 or 14, you can see that same PCB identified  above and to the right of the smoke unit (square box with a square reservoir), also up and to the left of the front truck.

Perhaps you may be thinking of the metal leaf contacts, shown in the upper right of the cylinder assembly, sort of 3 switches in parallel? They are the chuff contacts for a sound system that uses them, although they are unreliable. Unfortunately the drawings do not show the wiring to these chuff contacts.

That is all that I can think of... perhaps you have more switches due to some additional user-installed electronics?

Greg

No offense, but did you look a the first page of the link?

look in the lower right corner, see the switches?

They are behind the smokebox door

Much nicer, although I don't see the socket inside, so probably the non-motorized unit you saw, no electronics.

Greg

Just took a new C-19, removed the coal load, and the "DC plug" and plugged in a QSI, everything perfect, including physically synchronized chuff.

And the K-27 was fine except you have to invert the chuff signal.

The C-19 is the best loco Bachmann has ever made, hands down.


Greg

OK, so  I think I follow now...

If you look at both diagrams, and you read German, you can:

• look at the bachmann wiring diagream
• follow the wires to the pins on the drawing of the Lenz decoder
• now look at the Lenz document
• see what pins are defined as (In German)
• using this translation to map to a different decoder

Not only is that a ton of work, notice the wiring diagrams tie the common for the lights to one of the pickup wires, not the common provided by the decoder.

Really not a good idea at all, as the #1 cause of decoder damage is accidentally connecting a track pickup wire to a motor wire, with all the translation involved just to further identify wires I think it's bad advice really.

Even more damning is that often locos have wiring errors that allow them to run on DC, but when converting to DCC you find a problem, as INDEED I have mentioned and personally experienced in a Connie.

There was an internal connection deep in the boiler between a track pickup wire and a motor wire. Most decoders can be destroyed.

This is why I always recommend verifying wiring with a meter when converting, with or without the main board.

Greg

Stan, did you read the thread?...

I already posted the manual, and how does a German manual for a Lenz decoder help a guy with a Bachmann?

Page 3 has wiring for the Lenz 230 decoder, nothing Bachmann.
