thanks Todd. A photo would help but I think with the help of the website I
can maybe figure it out. As I said in the other post, I could not find where
the wiring for the headlamp went. I was thinking I might install a backup
light in the tender while I was at it, and since it looks like I am going to
be doing some serious rework, that is a good idea.
I have another Y I want to upgrade that someone already re-geared with
Northwest Shortline parts I believe. I have not look at it close enough to
see if it has the cab-mounted motor or center-mount, but it already has a
backup lamp that works so I am thinking a lot of the PITA wiring work for
that unit has already been done by the previous owner.
Thanks for the help.

Yesterday I converted my Rivarossi Y6b to DCC. I found an installation
guide for a Rivarossi Challenger(http://www.wiringfordcc.com/hrchlngr.htm)
and noted the existing wiring diagram was the same as the Y6b. The new
wiring diagram will be illustrated on the said web page to answer your first

The headlight was the only minor pain as the existing headlight was
grounded to the frame. Took about 20 minutes to add a grain of wheat bulb
and route the wiring proper. Drill a hole in the vertical part of the
"housing" to accommodate the wires for the new bulb. The clear plastic piece
that is the headlight lens will have to be trimmed at the elbow. Headlight
assembly should fit back with the help of a little glue. I can forward you a
photograph later on in the day to clarify.

I need a little help here. I have three of these. I am planning on putting
DCC decoders in them. I have one of them open on my workbench now. I need
help in determining:

A) which wires are for what - from my eyes it LOOKS like the motor gets half

its power from a pickup on the engineer side wired to a contact on the motor

and the other side of the power through the locomotive frame to the case of
the motor. I have figured out how to isolate that to get to the DCC decoded
I think.

B) how does the headlight get its power? I can see one wire that leads from
the motor case to the front. Therefore I am assuming the other half the
bulb's power is also coming from the frame? I am scared to tear the thing
apart much more without knowing what I am doing. I had a lot less trouble
putting a decoder in an early 60's Mantua Pacific in the course of making
N&W #578.

Any help would be appreciated.. feel free to post it here or email me
directly at bob at firedogwireless.com. If putting my email address in this
post is taboo, Mr Moderator, please edit it out and send the post on... I
really want to run something other than a J, the E2 or an inappropriate
2-10-0 on my newly-updated to DCC layout....
