I think I figured out why the 2026 smokes on the test bench with my CW-80 and not on the track with the Z4K. I took the CW-80 over to the layout, plugged it in and connected it to the inner loop track with alligator clips. With nothing else turned on, the engine ran and smoked.
So it was either the Z4K was defective (probably not) or the Legacy and/or DCS signal being transmitted to the track through the TIU was interfering with the smoke signal. I think that's what it is. Not sure if anyone else has experienced this issue where everything works except the smoke.
I then clipped the CW-80 leads to one of the track power drops and it worked again, so I'll probably just hook up a small transformer in order to run conventional, with a few more connections to the power drops. Since the two loops are electrically separated and each controlled by a separate handle, I should be able to run conventional on one track and command on the other at the same time.
As to the headlight bulb, it is an 18v bulb. I was able to get a 12-16v bayonet bulb and it now runs brighter.
I'll post a video as soon as I get a chance.
Thanks, everyone.
