Title: Round circuit board on the end of Toby's motor
Post by: Grapevine Flyer on July 09, 2017, 04:24:20 PM
I posted this question in the Thomas section and got no replies.

I am modifying a G scale Toby to run with a BlueRail board. Inside Toby, a set of orange and brown wires lead to a small round circuit board on the end of the motor. It seems to have some resistors and a few capacitors. What does this circuit board do? Can I leave this circuit board in place? (BlueRail uses the same pulse-width-modulation to run motors that a decoder does to run motors).
