@kj356 posted:I assume that you have removed the sound board and reverse board from the Williams engine and it is completely the LionChief board for the sounds and control. !
Which speaker did you use the Lionel correct speaker that goes with the LionChief board or the Williams speaker? they may be different specs?
And did you put the things (what's the name????? diodes or resistors forget) on the motor that Lionel has on theirs to cut the noise from the motor? I think you need to use the correct parts for the motor draw to ensure no interference. I have found these different on the various Lionel LionChief motors.
Perhaps someone has more electrical knowledge to help you but I have done a few conversions myself with old boards and have had varied results but nothing like you are mentioning? Though my Williams engines have made odd sounds randomly before on their sound boards.
Good points, on many of these early Lionchief engines, there are 2 small inductors in series with the motor- in theory to reduce EMI/RFI. I have found that in some installs or retrofits (basically this topic) that if you omit those and get range problems from the remote, this might be a valid fix.
Again basically Lionel in most RF only style Lionchiefs did add inductors in series to the motor.

Again, they used 2, both leads of the motor.
