    I was wondering if the typical DCC locomotive decoder is happy when it's not connected to motor? I want to use a DZ143 to control effects in a passenger car.

    Second query: does anyone make a 4 function-only decoder the size and price of a DZ143?

    Thanks,

    Mark

    You need the "TCS Train Control Systems 1004 FL4 Function Decoder"


    I put one of these into a surfliner cab car for full lighting effects. Crossing / ditch lights, headlight and tail light.

    Mark,

    No problem using the DZ143 for functions only (no motor attached, only lights and accessories)

    Best,

    Thanks. I'm actually more interested in controlling the restroom lights, dining room lights and kitchen lights, and maybe a bit of animation.

    Rob(A),
    Thanks also.

    Consider this: you can always use the motor outputs as an extra function decoder - and it acts like a rheostat where you can reverse the polarity, so you can run the lights slowly up and down with throttle commands; or add a bi-polar two color LED and you can change the color of the light.

    I think I'm OK with the lighting. My main concern was with BEMF and such if the decoder would throw fits if it wasn't connected to a motor.

    I'm afraid I've almost become a fanatic for detailing the AZL heavyweights. When I was a kid, American Flyer did a walking brakeman boxcar: http://www.trainweb.org/s-trains/numbers/25049.jpg
    and I'd like to try something like it in Z: perhaps a porter in the 12-1 or a waiter in the diner. Don't think I need too much detail beyond the motion.

    The only problem we have run into its the locksound decoders. The sound will not work if its not hook up to the motor. It works fine on diesels, but it needs to be hook up for steamers.

    Uses back EMF to time the "chuff" sounds? (Motor speed?)

    THAT WOULD BE SO COOL!!!!!!
