Have a new to me SHS 2-8-0 AC/DC sound- unit does not reverse with regular flyer transformer. Have set all the dip switches to off. Any ideas why this might be occurring?
Thanks for any help

The AC/DC sound unit was made by Dallee Electronics.
It's been a while since I played with one, but I think you need a Loco-Matic controller to reverse the locomotive, which will also allow you to control the whistle, bell and headlight functions. SHS included one with their Loco-Matic F-units, but I think they left it out on the 2-8-0's.
An email or call to Dallee might answer your question.

Doesn't need locomatic- it should run fine on conventional
Do you have your instruction manual? It should tell you how to set the switches for conventional operation. I don't recall what the right settings are, and my Loco is packed away currently awaiting me to have the time to replace the split gear on the drivers
Here is a link to the SHS 2-8-0 Locomatic Users Manual. http://www.nasg.org/SProductGa...C-LMInstructions.pdf
Below is an excerpt from page 9. Based on my experience, try moving each dip off and on several times gently with a small instrument (preferable not metal). Sometimes the dips loose positive contact over time and need to be moved a few times to restore that.
From page 9 --
With all dip switches in the off position a start in forward with standard AC operation will occur. With dip switches in the off position when power is interrupted, a second will pass before sequencing into neutral (especially with low voltage)....
You say you are using a Flyer transformer . Are you sure the voltage is dropping to 0 ??? I have an 8 B that does not drop to 0 volts. You must have 0 volts for the reverse unit to cycle. Post what transformer you are using.

I assume that you are lifting the handle . Even so, they can still have voltage .With handle lifted, check the voltage at the track.

Bob - I thought that lifting the handle on any of the "deadman" transformers would break the circuit (so voltage should be zero). Doesn't lifting the handle allow the roller assembly to 'spring up' off the transformer windings?? At least that's what they are designed to do. All of mine - 30B, 18B and 15B - do.
Yes , if they are working correctly. We had a 30-b on our club layout that didn't work right , just a small amount of current was bleeding through. We had bought it used . We did get it corrected.
