wait for instructions from DALE H.

I agree. Not a lot of room for adding a string of diodes. You could try wiring the motors in series. That would be a lot easier.
Do you run TMCC?
All you have to do is add a R2LC board inside and now your loco is ready for command control.
You can also add a cruise commander M which would give you improved slow speed performance.

What are you hoping to achieve?

Hi Terry

 

I can not comment on fit. Might be some room in the center. Might be able to bend it U shaped and fit it around a motor.  The wire nut do not help. If you get stuck E mail me,I will make you up one with some 3 amp diodes and send it to you. 4 or 5 pairs,whatever you need. This may work a bit smaller.

 

 

 

As far as where. The yellow wire goes from each motor into the PC board. If the motors are in parallel, they should go to the same place,electrically speaking. Cutting each yellow wire from the motor,they should go both to 1 lead of the diode string. The remaining 2 going into the board would go to the other end of the string.  I ASSUME this is how Lionel does it with their color coding. Dont hold me to it. 

 

Going to bed now,will check in tomorrow evening.

Wow, appreciate the offer, and YES I WILL HAPPILY SEND A CHECK TO YOU,

my email is in profile, and I'll shoot a note to ya. Yes, I put the top back on the loco, but will take off again this week -end, as to what you are explaining about the 2 yellow wires, seems pretty simple, and I do believe I need to get you better info, concerning those yellow wires-- need to follow the connectors. I just need this one application for this loco,  ALL others are MTH, or Williams ( which need nothing),  or non smoke applications. 

My authoritis, says thanks, also.

Terry

 

Just send me your address. There is no charge  for it.

Dale,

If you recall, because of space issues, I wired the diodes in a circle like a donut.

Maybe that would work in the center space here.

Yes you can bend them U shape or in a circle. From the pic I see some wire nuts used by Terry. Might make things less flexible.

 

I made one out of 2, 10 amp bridge rectifiers and sent it to Terry as well a diode string one out of 3 amp diodes. Hopefully one of these will fit in and offer about a 3 volt drop.

 

Dale

here are a few pics with success all due to your assistance.

 

Hey, Guys, 

 

I went ahead and popped the top again , getting ready for the mail man,

and as you can see the pic,:   

   1) the left side nut, has the Yellow wire from the back motor, ( right side)

       and the blue wire from the front motor, you can see it coming out of the top.

       green wire is going to some board there in the middle,

    2) the right nut kinda of opposite information,  the Yellow wire is from the front

        motor ( you can see it goes under that tape on top of what ever board that is)

        , and the blue wire going to the back, motor. 

     again that green is going to the board, and so is the other blue, 

  so  we wait and I'll announce when it gets here,   Appreciate,  wish I had known this  I would have bought an  MTH,  thanks,,,,,,,,

All right the bridge rectifier, and The diode string is here. 

As we have discussed, due to space,  I'll go with the recitifiers, after I put

black tape around it.  BUT,  I want to be sure, that I am suppose

to put this in between those Yellow screw nuts that are connecting

the motor wires,and wires to the boards. Do not feel like blowing an

engine less than 3 months old----   1 hour later,  The train does, go

However,  I will need to just use 1 rectifier,  as the 2 cuts down loco

where it will not make it around curves,  will let you know in a few!!

thanks
