New Style Bachmann 4-8-4 J Decoder Install Link?

[billincarmel]

I have finally got my 4-8-4 J to run like a Swiss watch thanks to another forumer. I want to install a decoder and I would like a step by step link if one is available. Thanks in advance!

hmmmm
I think there are solder pads or jumpers in the tender.

there are 6 wires to the tender.   
So some how,  the tender can be installed in the tender.

I'll have to look in there tonight.

Hi Bill,

I went and looked at a J tender

there are solder pads  
they are numbered  just like the heavy Mountain  so any
links about the Heavy also apply to the J

the pads are numbered 8,1,2,4,5,6,7.

the jumpers connect 8,1 and 2  
and connect 4,5,and 6  with 7 not jumpered.
the two jumpers must be left and right

there is a DCC specification that comforms
to the pad numbers, If that is not enough I'll hunt for the
color wires that conform to those numbers.

look for Heavy Mountain install information also
is mainly what I am saying.

eta
1 motor - orange
2 reverse light - yellow
4 power left - black
5 motor - grey
6 forward light - white
7 light common -blue
8 power light - red ( I think light = right)

check the paperwork that comes with the loco.
basicly solder the decoder leads to the numbered pads
be careful because the first pad is 8 followed by 1 ....

Installation procedure solved. I only had to open and look at the Bachmann parts list. It shows a detailed drawing of the board and connection points. I should have done this in the first place!
