There are many old threads on re-wiring a Williams loco in series to slow it down. Mainly after adding a ERR sound board so it will operate with complete sounds, motive, horn, and bell, at 0r below 10 volts AC. Can anyone answer exactly that after wiring the motors in series, that less voltage is required, and the engine will run slower so the sounds can be activated accurately. All input is welcomed and appreciated. Thanks in advance for your responses'...
