Uhh.... yes, I was replying to your question to the best of my ability.

You may want to do some additional research with the manufacturers directly, and also confirm the sizes since no one has reported the physical clearances around the socket.

Heaven knows what they tested it with, most likely the OEM Tsunami.

Greg

Good for you, keep those gray cells going!

On the Climax, yes, I gather you are thinking the AirWire CONVRTR, and you should be able to re-use the dcc board, but the wiring will be a pain, since you would want a socket for the DCC board removed, and also you will have to connect a number of wires between the tender and the loco.

Now that I re-read your post, what you said makes the most sense, battery in tender, connect to CONVRTR, then you need to route the CONVRTR output to the loco, and feed it's outputs to the track input wiring... (and remove the track pickup contacts just to be sure).

That should be the simplest install.

I'll watch this forum for your progress, and best of luck!

Greg

The compromise between keeping the original board for wiring simplicity and removing it to get more space is a decision that can go either way.

There are pro's and con's to teach way.

By removing the board, you got a lot more space in the Shay for electronics and/or better speaker.

Not sure I would remove the board in the C-19, it's the best wired, best documented loco Bachmann makes.

The Annie depends, usually if you try to keep the flicker board.

There is really no wrong or right way, but if it works well for you, then indeed that was the right way for you!

Glad you rolled up your sleeves and got into it. Much better when you personally understand the install.

Greg

I agree with the comments above, look for motor or geartrain binding. How much current is being drawn?

Disconnect the phoenix system and measure the draw.

By the way, realize that the MRC6200 is a marginal transformer (under 2 amps) and also subject to failure. So measure the current drawn, you can buy a digital meter capable of measuring up to 10 amps for $5 at Harbor Freight.

Greg

If you can find a used QSI, they are great (I have a lot for myself and will program them for anyone free).

The Phoenix is OK, it has some limitations, but mostly power, and the Big Hauler should be no issue.

I would not buy the Digitrax DG583 (I think that is the number)

The TCS Wowsound will work, the early versions were not great, I think they have improved the firmware.

I believe you should be able to buy one of the OEM SoundTraxx "quasinamis" that are derived from the Tsunami.


Greg

I would think so, but you will probably have to use autochuff... or wire the electronic sensors to the Revo board.

I agree, that and possibly the multi pin connection between the loco and tender.

I like it has the optical chuff sensors in it now, synchronizing the chuffs exactly will be a breeze, no more unreliable physical contacts.

Greg

I'm wondering if that brown coupler will be black in production...

Yes the PNP with the socket in the tender must have a multi-wire connector, just too much "stuff" to connect to.

Well, we are now waiting on seeing a real production one..

Greg

Ted, I know you are exercising extreme restraint, you waited an entire day until you asked again 

From what I am told, the Bachmann display was on a table at the Star Hobby booth. A friend asked about the socket in the new Big Hauler, and they were not aware of it.

I guess that's what happens if you don't represent your product yourself.

Greg

I completely understand Bill, our nomenclatures differ because yours are chassis specific, and I look at it for the total feature content, although early models were mostly predicated on the geartrain changes.

I get ya!

Greg

Did you use the BBS embed code with my links?

That's the way, I was trying attachments....

Greg

Since most people track the versions as version number or generation number I will call it gen 7.... with the PNP socket as this is a big improvement.

As I said Bill, you can see by the links, they reference YOUR emails, which of course only you have access to.

Ted sent me a couple more pictures:

all these pictures are on my "Big Hauler" page, but the 7th Gen is at the bottom of the page.

(It's about impossible to upload pictures here, the file size restriction says 192k, but then 128k, and then it "broke" saying the buffer was full...)
