Thanks. Actually I did mean the TSU-AT1000 (#828041) and speaker (#810113) which I just received today along with the corresponding enclosure and gasket kit.Josh,
I have done thousands of installs.
Red flags went flying on your post because the Bachamnn SD40-2 does not take a TSU-1000 decoder. It takes a TSU-AT1000 #828041, and speaker #810113.
You have to install the LED's and make a speaker box for it too. It's a fairly easy install.
I got it (and the rest of the items) from Litchfield Station www.litchfieldstation.comWhere did you get you enlosure from? I haven't been able to lacate any in a while.
The wiring instructions for the TSU-AT1000 are pretty strait forward, PM me if you run into a problem.
This is where I will be posting about how to install a Digitrax DH123D DCC decoder into a Bachmann Spectrum Line GE 44 Ton Switcher Yard Engine.
Examen the insides of the Bachmann Spectrum GE 44 Ton Switcher and plan where the DH123D DCC decoder will be installed.
Engine with the shell on.
The engine with the shell taken off to expose the insides of this intricate switcher. Note that this switcher has two motors intead of the normal one. While this greatly improves pulling power this also makes the install of the Dh123D more complicated and compact.
For the placement of the DH123D I am planning on putting it in the center or on one of the sides. there is currently no extra space in this engine so I will have to grind away a lot of the wheight to make room for the decoder. This limit on space will also increase the amount of difficulty that I will have installing the DH123D DCC decoder.
Had a major mishap today and fried the DZ123 decoder for the 44 ton switcher. I have not figured out if it was the fact that I had two different pickup points or the fact that I am wiring it up for two motors. I am thinking it was the first one and am going to the train store tommorrow to get another one. Other than that I have to install the two lights and it will be finished. Then I will upload the install guide for this engine.
More updates to come...
