Williams - Wiring In Series

it's really pretty simple.  Just take the cab off so you have access to the motors.  Then cut one wire to each motor, but they have to be the opposite poles on the motor.  In other words, cut the "hot wire" on one motor and the  "ground wire" on the other.  Then connect the two open motor leads together.  If you cut the wires with enough wire, you might not even have to add wire;  simply splice the two leads together.  

If you happen to do it wrong, and the motors are running in opposite directions, it's an easy fix.   Just cut the other lead for one motor and reverse the two sides.

Since this is a frequently asked question ADCXXROB's response should be pinned at the top.  That is the best solution.

I've done this to several Williams units, SJC.  Great results! Slower speed, brighter headlights. I can show you next time we are at a show simultaneously.

There are those who say it is better to use diodes, though.

Thanks all.

Bill - Thanks for your offer. I'll probably take you up on it, maybe at Gaithersburg! Appreciate it.

I've wired some of my Williams in series.  They do run slower and on my RS-3, it improved the volume produced by sound system.  Still no as load as I would like.  This is an area that Bachmann could improve upon.

I have a Williams F-3 that I'm considering adding an Electric RR sound board to.  Any opinions on how well this would work in comparison to a Bachmann sound board?

BARAILROAD: It is not an F3, but here is a Williams Genesis with ERR sound board added.  I like the fact  that one can vary the horn.
