Parts arrived yesterday, I have attached a color copy of the article. I should have all the colors marked correctly, the lighter color appears to be grey, white is white, black should be the darker color and red/green appear to be tied in together.
Using a ZW transformer and looking at the drawing since it shows Red/Green and Black to 12V AC or DC I am confused as to placement of Blue, Red/Green and Black. Blue could go to A or D (throttles on transformer) Red/Green could go to B or C and Black (common) would go to U am I correct?
It might be easier to have a separate 12V AC power supply for Red/Green, Blue appears to be supplying power to all relays and track power/left/right section.
What do you think? I think I have it correct. Used to working with automobile schematics, parts manuals,
