Be sure that your locomotive’s motor is completely electrically isolated from the chassis. The decoder’s output to the motor is processed from the power received from both left and right rails. If either pole at the motor is in contact with either rail, it will create a short path, that can ruin your decoder.
Also, it is important to know that your locomotive’s power demands do not exceed the decoder’s power capabilities. Example: If your locomotive takes 1.5amps to run, and your decoder is only rated for 1 amp, then the decoder will be overloaded and possibly damaged trying to handle too large a load. Many older locomotives, especially open frame (non can motors) will draw lots of current. Be sure to select the proper light bulbs that won’t exceed the function outputs rating also.
