How-to re-wire Williams by Bachmann engines into series????

[KRM]

 

Hi,

 

 I have this Williams by Bachmann Burlington Northern SD 90 Locomotive # 9587 that is a great engine but,,,,,,,,, when I try to run it slow on my upper reversing loop it requires so little power that the Lionel 0-42 Remote Right-hand switch does not have enough power to work before the train gets through the switch.

 

 This engine will fly and here is the question.

 

I think I saw somewhere here how-to re-wire Williams by Bachmann engines into series or something to slow them down. That would allow me to apply more power to the track so the switches would flip faster.

 

Thanks in advance for any help!

 

Kev.

wish I could help. I can do it but need a williams engine in front of me to do it. And don't have one at hand at the moment, all packer away

Remove the yellow wire from one motor, the blue from the other. Wrap them, separated, with insulating tape and secure them inside the shell. Now connect the two motor terminals you just freed up with a new wire. Done.

 A DPDT switch can be installed, too, if you want the capability of switching between series/parallel.

Thank you ADCXRob!!

  The series wiring was easy and did the trick for the switch. Slow speed is now a crawl and there is still plenty of high speed. A much better chance of the grandkid not flying the engine off the upper loop!!   

 

Here it is running .

Kevin, your layout is great!

Thanks Buckeye. That means a lot coming from a guy with as nice a layout as you have.
