I looked at the wires that were all soldered together, and something doesn't add up. Two of the wires are connected to the truck grounds, another was connected to the "off" position for the odyssey switch, and another was connected to the AC regulator. The wiring diagram doesn't show any of the wires coming from the AC regulator to be connected directly to ground. That wire should go to the "smoke on" terminal. Furthermore, a different wire from the AC regulator is soldered to that terminal, but the diagram shows that this wire should be connected to the third rail pickup. I removed the smoke unit when I first disassembled this engine so that it would be out of the way, but I remember the smoke unit turning on immediately when track power was turned on. I'm pretty sure legacy diesels aren't supposed to do this. I don't know if this could be connected to the DCDS issue, but somebody definitely made a mistake when putting this thing together. I'll keep looking for other errors before I fix this wiring issue, just in case I missed something.
