2343 wiring problem

Some of the MPC e-units had wrong wire color coding.  The green wire, which is usually the field wire, is connected to the center fingers.  The wire from the outer 4-finger contact goes to the field, the center 4-finger wire and the bottom 2-finger go to the brushes.  You can advance the e-unit manually and note if the fingers touch the drum contacts in all 4 positions.  You can adjust the pawl or bend the fingers if they are not making contact.

Does it cycle F-N-N-N-F-N-N-N?  (There are 8 positions on the drum).

Thanks for the help to both of you. Jong- I suspect it is the new eunit based on your comment.  I am not familiar with electronic terminology such as "field wire" etc. I am asking a favor? I usually get it after I see a picture-especially if it is color. Is there a way you can color code a picture of the wiring how the wires go to the tops of the motors and back to the eunit?

Then it is easier to proceed. The motors are balanced nicely (equal rpms), very aggressive forward motion, strong magnetraction, but no reverse operation. I am attaching pictures (side view and top view) of the current wiring setup for you to review.

Best Regards!

Switch the blue & green wires at the motor and you should be good to go. The blue is for the field connection, the rotating drum alternates/swaps the green & yellow to the brushes for direction change(with a neutral in between each state).

Dear ADCX Rob- Just got around to doing the wire switch like you said. Works perfect! Matched High RPM , very strong pull both directions. Will be a 2368 ABA Baltimore and Ohio.

Sending a couple of pics. Lionel Postwar F-3's are my favorites.

Best Regards
