I bought a used one that looks like the above picture. No power is coming through the Variable 2 port. I tried changing it to fixed and still no power. Are there fuses and if so, where or will it be a diode gone bad as mentioned earlier in the post. Also I have another question. I have a trolley I'd like to run at a slow speed. Is it possible to hook up a transformer at a lower output to a fixed channel so it will just run at a constant speed. I already have 2 other line that truly will need the variable output channels.
Thanks,
Eddie
