I am trying to wire a 2 position e unit ( new style) to a Lionel 218 Sante Fe. Can anyone give Me a diagram or description on how to wire the unit to the motor. Thanks for any help!!

It can't be done without changing the motor field to a double winding unit. OK, well it can be done, but with only neutral and your pick of forward or reverse.

Thanks Bob , it seems the motor I am trying to wire to is a double winding unit. Can you tell me how to wire up unit..... thanks .. Joe

The motor is wired incorrectly.
The black wire on the right from the reverse unit to the motor brush is wrong. It should go to one of the coil wires.
The red coil wire wire should not be connected to the brass terminal screwed to ground on the left side of the motor.
Connect the red and green coil wires to the left brush connection.
The red and green coil wires should be wired to the switch, one on each terminal.
Power in should go to the right brush connection.
Follow the wiring diagram and your loco will run.

Here is a color-coded diagram showing the connections. The blue solder tab is a strain relief only, like the center maroon connection on the brush plate, and CANNOT be grounded(yours is). It is supposed to be a shouldered insulated washer here to keep that tab from grounding out on the screw.
Thank you for all your help Rob. I Really Appreciate it.
Attn: Rob .... a follow up to your directions and diagram... the loco does operate.. the e unit does not seem to engage... loco functions in one direction only... I have tried to toggle e unit switch back and forth with no results ... any thoughts.. thanks in advance for your help... Joe
Don't toggle the switch. Leave it ON. Does it go, then neutral, then go, the neutral when you interrupt power?
And then, show a picture of how you repaired this improper ground:
That Solder tab is supposed to be an anchor point for the single red wire and the black wire that are floating off to the side. This is to prevent the turning of the motor truck from fatiguing the field wire and breaking it off. Once you get it running, make that mechanical connection.
The white wire is supposed to be connected to the collector/rollers for power to the bulb and reverse unit, on the brush with the black/white wire(from the rollers).
The other black wire floating around there connected to the green field wire is supposed to be connected to the other solder tab between the brushes as an anchor point to prevent the turning of the motor truck from fatiguing that green field wire and breaking it off. Once you get it running, make that mechanical connection too.
Thanks Rob... project for tonight.... will follow up and thanks again..Joe

Okay... as you can see I made the connection as you said. The engine runs only in forward,however, the e unit still doesn’t seem to function correctly. Sometimes power on and off and it will start in neutral position . Then direction handle and forward and that’s the only direction. I notice the drum in e unit does not drop down. Could the e unit be faulty??... Joe

That's a 101 style reverse unit, not an e-unit, it is forward & reverse only, no neutral.
Try it with the switch on top "off", push up on the solenoid(red arrow). The pendulum switches/alternates left/right - forward/reverse each time you push straight up at the red arrow. The switch on top just turns the solenoid on or off, it has no effect on the direction.
O’kay Rob I put the switch off and move the pendulum left and right and loco only moves in one direction. ..... not sure what to do ... Thanks ...Joe

Does it hum when it doesn't move?
Now swap either the two black wire connections OR the connections to the two brushes and test again to see if it goes in the opposite direction.
An additional problem you still have is this screw, it must be completely insulated from that solder tab or the engine will only run in one direction. Sometimes, Lionel even used a plastic screw here.
Okay Rob..... good news finally got the engine to go in opposite direction. Now it seems the solenoid hangs up . Barrel won’t drop down. Once I bring it down it goes in the opposite direction . Any thoughts.... Joe
Clean with contact cleaner spray - somebody may have erroneously lubricated the solenoid plunger. If it's binding, it may have overheated, and needs to be replaced, or disassembled & reamed. Usually it's just dirt & grime built up after somebody squirted WD40 or something in there.
Thanks Rob..... I will give it a try....
Attn: Rob .... I did as you said and sprayed with contract cleaner. Upon testing the loco it will operate as it should forward and reverse 2 or 3 times and then get stuck in the reverse position . It appears the barrel is energized in the coil and somewhat difficult to bring down. Once power is off I can tap coil and it will drop down. I have reverse the wire connections as you suggested but no change. Is it possible solenoid is defective?? Still nice to see unit run ..if only for a couple of seconds.. thanks ..Joe
The 101-1 reverse unit is easy to find, just replace it at this point.
Hi ADCXRob you got me wondering would it be possible to make a 3 position e unit go forward / neutral only ..? or reverse /neutral only.?
I thinking if you ground the one (say blue wire)to the field and both wires to the other brush side say yellows/blue) . I think as long as the field/brush wire is correct it will cycle in that direction and go to neutral/ forward(or only reverse) when you hit the transformer control button......daniel
You can get F-N-R with a 3 position E-Unit. Here is the wiring diagram... use only the red field wires or only the green.

Thanks Rob for all your info.... if inspiration hits me I might try to wire up a 3 position e unit with your diagram.
