I'm installing a Soundtraxx 3TSLC in my HO 3 Truck Shay, but am not clear on whether resistors are needed for the head and tender lights to prevent burning them out. Can anyone help?
Roger:
The decoder you mention plugs into the factory circuit board, which already has the resistors on it. So, no need to add more.

Thanks John - I'll plow ahead.
