This is why I love older Lionel locomotives, they are easy to work with... All you need to do is rip out the e-unit and patch up the circuit you just broke...
On the left side, you have two wires (red and bronze) going into the e-unit... I am assuming that one of those comes from the smoke unit and the other comes from the pick-up rollers... On the right side you have three wires going into the e-unit... The two wires circled in blue are for the two brushes, and the wire circled in red goes to the coil... What you need to do is connect the wire coming from the pick-up rollers to one of the blue circles, and then connect the coil wire to the other blue circle (in the picture, connect red with blue, red with blue)... Now, I am not sure which of the red circles go with which of the blue circles for your particular motor... Just try it one way and you will know if you have them mixed up because the locomotive will run in reverse
The easiest thing to do would probably be just break the wires off at the e-unit, connect red to blue and red to blue, test it out on the track, and if need be switch them... Then you will know that when you solder new wire in that they are going to the right places...
As far as connecting the smoke unit, you can either tie it into the wire for the light (I do not see that in the picture you provided) or you can extend it and attach it to the same blue circle you attached the wire coming from the pick-up rollers to...
PS: I hope that was not too confusing, I really suck at explaining things
Hmm, IDK... I can guarantee you that it does not need the e-unit to work though...I tried it but it didn't work.
It used to groan but now it's dead silent.
I tried the wires in other arrangements with no luck.
Guess it needs that e-unit to work?
It is possible... I would need the locomotive in hand to look it over... The wiring may be bad, it is also possible that the wiring elsewhere is bad... Do you have a multimeter to test it? Maybe T-Man will be on soon to chime in on this...Maybe the motor is gone?

Just to be 100% sure, these are the wiring setups you tried? I should have drew this picture in the first place, LOL
Yes, that's it.
The pickups are working because the smoker works.
I'll rig some alligator clips and wires tomorrow to check for life.
Maybe the motor is toast.
What's bad with the eunit? Did the drum break?
B&M the wiring looked ok. It's a shame to do this to a nice engine.
You will have to check if there is a short between the armature plate and shaft. You can do this with a powered test light.
Might need this
That's easy---they were mounted in backwards of course.Wow, where are those brushes
That's one for the books. The engine, overall looked really clean and in great condition. Hope it works out. I think you found the problem. Whew
Here is how the e-unit works... It is quite the setup...Oh, I found out what was causing the e-unit to act-up. It's the tender. For some reason when I use the original tender it sparks and causes the engine to shift directions. Maybe an electrical problem?
