regarding Load resistors across the motor circuit





I hope to use T4X decoders for lighting on some Broadway Limited Sound locomotives to bypass the factory lighting. One needs to install a temporary motor to program the decoder. Can I use a resistor as a permanent motor load? I had one dealer suggested a 22 or 100 ohm resistor. What do you recommend?

You can attach a load resistor to the T4X motor output only temporarily for programming on the programming track. We do not recommend leaving it in for normal operation. If you left the resistor installed it would generate heat when running. The heat that it will create could melt/warp the plastic shell and generally overheat the decoders.
