Hi!. I'm new to the forum, so be easy on me. I'm also new to DCS systems. I just got done with installing A PS3 up grade in a PS1 rail king 4-6-4 Hudson steamer. The kit came with everything you need. I have two problems #1 no smoke for stack, It smoked before upgrade. I cut the traces on the circuit board to isolated from the electronics. The smoke unit motor is working fine blowing air out the stack. I check for power at the heating elements the voltage is there I checked for ohms at the elements reads 8.2. Now, I remove the circuit board form the unit. I put a positive wire at one end on the heating element and a negative on the other end and put power to them they worked Great, at any voltage I put to them. My question here is are the wirers going to the element both positive because I checked for negative on both wires and there isn't any. Problem #2 The DCS loader program won't load my proto sound file will not download to the engine. I get a message can't find engine command board, I tried more then 6 times, Just won't download. I'm using a RS-232 - USB cable. It's finding the TIU connection, But won't download sound file. I took some pictures of the engine and tender.
Hope this expands everything. I'm from the postwar times and I'm trying to build a O gauge layout for my grandson he's only 3 but time I get this done he'll be 8 or older!.
