Hello all, I am well versed in Lionel Standard Gauge engines of all ages however I recently bought my first Ives engine #3241locomotive and I'm trying to get the manual reverse lever and motor working again. This motor is very different than a Lionel Super motor and I'm having trouble figuring out a couple things. First is that the manual reverse unit is in bad shape. The fingers that touch the drum are very loose and constantly short out. I tried sanding them and tightening the screws but the motor keeps shorting out no matter what I do. Interestingly when I removed the manual switch I could get the motor running by connecting an alligator clip to certain fingers but it doesn't make sense to me. Next I tried to wire it to an extra Lionel #8 hand reverse switch I had but the short outs got worse. I think it has something to do with the 2 wires coming out of the field windings instead of just one like in all Lionel motors. I have never seen this before and I can't figure out which switch terminals to place them on to make the motor work. I have found all the wiring diagrams available but the only one that shows 2 field wires was meant for an Ives original electric E unit and not for the manual version. Any help would be greatly appreciated as I saw this engine take off down the tracks only once. So I know that it works but I just can't figure out the right wiring for it. I'll post pictures of the actual motor and thank you for your assistance!!

In looking at the wiring diagram it indicates that Ives grounds one brush holder and reverses the field leads. This is the less common way of of connecting a motor, but it works fine. In looking at the pictures one brush holder has what looks like an orange insulated and the other appears to be grounded to the metal brush plate. That is consistent with the drawing. That being the case, it appears that the large white wire is a dead short. It needs to be removed.
At the reverse switch the the two field leads should be connected to screws across from each other. In the picture it appears they are connected to screws next to each other. That will not work. Once the field leads are connected to screws across from each other, the power lead connects to one of the screws between the field leads. The brush, small green wire, connects to the other screw between the field screws. Power screw is opposite the brush wire screw. It does not really mater which screw is which as long as the wires are in the proper orientation.
To bypass the reverse switch connect one field lead to power and the other field lead to the insulated brush holder. If the motor runs the wrong direction reverse the field leads.
As david indicates , Ives motors are field reversing not rotor reversing like Lionel. This means the field is NOT grounded ... so dont look for it! top post...power. bottom post... brush lead. side posts....field leads. Easy japaneasy.
Thank you so much David and Rob I had never seen a field reversing motor before!! I can't believe I didn't destroy it the way I had it wired up!! After the changes Rob mentioned it fired up instantly and runs smooth as silk! You guys are the best!
