Rivarossi Y6b question

[nw-modeling-list at nwhs.org]

Wow i posted this more than a week ago.
I have since determined that i have one unit with the motor in the center 
and two with the motors in the cab. In either case it appears I have to do 
some modification to the frame of the motors at least on the cab-mounted 
ones to make it work electrically. I have not had time since I last posted 
to really forge ahead on this but I will make careful notes in case someone 
else comes along behind me needing advice, just as several of you on here 
have done for me. Thanks!

>>Hi Bob;

>>

>>Reading your note, I think that you have things pretty well scoped out. 

>>Both the motor and headlight get power from the frame.  You must sever 

>>those connections.

>>

>>Get out your multimeter, and make sure the motor and the light bulb are 

>>isolated, then hook up the decoder.

>>

>>You may want to add a resistor in series with the light bulb so that it 

>>does not get excessively hot and melt the shell.

>>

>>Which version(s) of the Riv Y6b do you have; motor in cab or motor in the 

>>center?
