Thanks Rich.
Mine are only marked Con1 and Con2

New question, same model tender.
I removed the trucks and did not pay attention to the insulated wheel orientation.

I took the trucks off, thinking I needed to, to get to the DCC plug.  It is a screw and nut, and the nut falls off under the coal load which is bigger than the opening at the top.  Somehow I got it out.
The truck mounting screw is part of the electrical pick up and both wires go to different spots on the lightboard. 

I have a diagrams of 88912 and 89841.  They show the insulated wheel on the engineers side.  Is that the way it should be or is one truck reversed?

I found a deal at a train show $79 for the Spectrum.  My only complaint, aside from the fiddly tiny plugs is that the headlight is dim and definite shade of blue.  With all the detail on the engine, I'm not sure that I will be looking to change that anytime soon.

Thanks

I have run across a Ma & Pa DCC ready loco with 2 different model numbers 52204 and 82302
What is the difference?
