Is it possible to reverse the wires to the can motors?

Would it be possible to reverse the wires that go to the can motors so when you go forward with the remote or app, the train will go in reverse?  Specifically with the Santa Fe Lionchief FT Diesel, from the set, 6-84719.  Wanted to put two of the FTs together in the normal "AA" fashion, but obviously one would be backwards so it would want to go in the opposite direction of the other.  If it would work then they would both be controlled with the remote working correctly, even though one would be backwards.

My uneducated guess is that the electronics sees the remote going forward and just sends the signal to the motors to spin one way, then the other way when the remote is in reverse.

I know with the ERR upgrades, the manual states if the motor direction is not correct, just switch the wires.

Thanks

I have many K-line diesels with can motors. They are mounted opposite each other and are wired accordingly to spin in the same direction. I would assume you can do as you propose. I wire all of mine in series to slow them down. The blue and brown wires off the board are the power leads to the motors. Yellow and blue are the hots from the motors. These show after I changed them to series.

I'm not familiar with ERR so someone who is may provide more info.

You could switch the motor leads to reverse the direction of travel, but take note of the fact that the couplers and lights would now operate backwards.

Yes you can. I bought one of the very first LionChief Thomas sets when they first came out.

After a year or so it was repaired for a bad board in the engine. When I got it back the tech had apparently crossed the motor leads somehow as when the remote was in "Forward" the engine moved backwards and vice versa.

Turns out all I had to do to correct it was switch the wires in the tiny plug that sent the power to the motor. The wires were held into the plug by a spring loaded plastic tab inside the plug. I depressed the tabs, switched the wires and all was fixed. No soldering required.

Maybe your engine will be similar so you can make an easy (and reversible ) modification to your engine.

Ok, I opened it up. 

The red/black wires go to the pick up rollers and the frame. (First Picture).

The blue/red wires first go to the back motor, then brown/blue wires go from the back motor to the front motor (Picture 2 & 3).

Would I only need to reverse/splice the blue/red wires, somewhere before it gets to the back motor?  I don't know if I can reverse them within the white connector.  If I can, that would be the easiest, if not, splice the red blue.

Before I do anything, I just want to make sure my thinking is correct.

If there are two motors then they are wired to spin in the same direction i.e. both will turn clockwise at the same time and vice versa. Otherwise the motors would fight each other.

I would leave the red/black wires and plug alone. Who knows what else they send power to and what would happen to sensitive components?

I think if you swap the wires AT BOTH MOTORS you will retain the paired rotation direction...it will just be the reverse of the Factory rotation direction.

GRJ would have the best info on your query.

I am able to switch the blue & red wire in the little white plug if that would work.  That would switch the wires to both motors.  I have not put power to it yet.  Waiting for people with more knowledge to chime in.  Like you mentioned in your earlier post, the white clip has little tabs that can release the wires.

What about the warranty ?   Wouldn't Lionel void the warranty if you switched the wires ?

Probably, but could be reversed.  Bought two sets with the intention of only keeping the engine from the second set, selling everything else.  Selling track from first set as well.

 Sets were only $258 each,  so after selling everything, and getting A bunch of kohl’s cash, the second set will probably be free, so I am ok with it.

That should do what you want, as well as being easy and reversible (no pun intended). Wait. I did intend that pun.

Instead of splicing wires you could have removed the motor 2 pin pug and using a pin lift the tab and extract the connector terminal and just swap places.  No soldering and easy to reverse back.  G

Jim, they do look good.  I bought a NIB B unit from 1993 of Ebay, should have it next week. 

Since I bought two set, I am debating on keeping the extra coaches.  Might want to renumber/rename them if I can.  The second observation car will be sold on Ebay, have one bid already.  All the tack will go as well.  By the time all the extras are sold, the second enging will be under $100.

The remote controls them both fine.  Turned the sounds off in one, but those 4 little can motors pull no problem.
