Need help with 2343 diesel motor

[ADCX Rob]

If DC is being used, they can be shunt wired. The current draw would be astronomical, though.

Think it all depends on the type of motor. In my case I have three points (connections) on the top. Others have two. The middle connection i believe energizes the field coil. Without it the armature will not spin. So once the field is energied then you must power the armature. Connecting power to the left or right brush then dictates direction...Or so I think thats how it all works. I'm more familure with the magnetic type field electric motor which only requires power to the brushes.  

If your motor runs with only one brush connected, then the windings must be shorted to ground. No Lionel motor was manufactured to run that way.

As was written by Lionelsoni, Lionel motors were designed to be wired with the field and armature windings (brushes) in series.

The armature should be wired in series with the field.  Don't connect the field winding directly to your transformer.  Even if you can get the motor to run with the field and armature in parallel, it probably won't run well; and you risk burning out the field winding.

 Yeah that sounds strange, I thought it was power to one brush. Jumper from the other brush jumped to the center tab and ground to the motor??

Lets Chill, Rob the diagram did not work for me. What did work was to power wire the center post on my motor (using transformer) ground to body. Then attach jumper from center post to left or right brush. Seems to work. Thanks for the Help. A great site for those not in the know...

Doesn't sound correct. What is connected to the brush that does not get a jumper?

[KRM]

djrmmr, Glad you got it figured out.

I don't need to chill,,Just trying to say we all need to think past what we take for granted. It is all good.

The "center" is not really a connection,

Maybe, maybe not? but all of my engines have something connected to your " not really a connection" from the factory with the 3 position E-unit.

So Rob, you are precisely correct but to the OP who asked the question do you really think he would know that? If he did he would most likely not had to ask in the first place. You guys got to remember, just because something seems clear to you with your level of knowledge does not make it true to the rest of us.
 Why I did not understand your explanation in the other post when I asked the same question till cwburfle  put it in layman’s terms. The diagram does not have the tab one sees when they are looking at their motor. And for us not at your level that will throw one off.

I hope he gets it before it get to TMI.  Live simple.

The "center" is not really a connection, it's a terminal point for the non-grounded field wire to be switched off with one brush or the other.

The "center" for your 2343 motor is the connection to the upper brush in the diagram, which can be made with an alligator clip lead on your motor.

[KRM]

Rob. Is that diagram only for a non reversing motor and not showing the center post where you need to jump to??

[ADCX Rob]

Use this diagram(disregard the bulb connection):

Reverse the brush connections to reverse the motor.

[KRM]

Put a jumper from one side brush feed to the center field tab and the hot to the other brush feed and ground to the motor body, Switch the jumper around to test the other direction. If I recall. I asked the same question for a ALCO motor here. I think they would be the same.

Working on a Lionel O gage 2343 diesel electric motor. Want to test motor which was removed from car. How do I hook up. Looks like three connectors. one at each brush then one in the middle. (field coil ?) I would assume ground is motor body. Want to test directions forward/back. How would I connect the wiring and how much voltage should I push through it.  Thanks for any help. Dave.
