TCS WOW decoder problem with MTH smoke unit

Chuck KOGR Forum Member

I installed a TCS WOW 501 decoder for steam and this MTH smoke unit https://mthtrains.com/aa-2100002 . However, when I set the CV for the smoke unit voltage to the lowest setting the decoder allows (setting 1 on a scale of 1-30), it still overheats the coil. I can't use a larger smoke unit because of the space limitations (I am an S scaler), so I am wondering if there is another solution such as putting a resistor in line with the hot wire that powers the coil.
