I'm having a bit of conundrum. I recently completely installation of a new signal on one of my mains.
It's an MTH single mast position light signal (30-11013) wired to a DZ-1075, which in turn is wired to an insulated section of track.
Here's where things become strange. The signal powers up just fine. When I roll cars through the insulated track the signal goes through the motions of stop, caution, and clear. The cars clear the block, everything works as it should.
Applying power to track changes things. When I roll a car through the block, the signal shuts off. However, once the car clears the block the signal goes through the traditional sequence of caution and then clear. There is no timed stop as there would be without power.
I'm not sure what the issue is here, as I have an identical setup on the neighboring track and that works just fine.
