Can anyone supply me with wire connections for QSI RU-104, reverse unit for can motor locos? | O Gauge Railroading On Line Forum

Hi all

I have a new old stock QSI reverse unit, but do not have the paper instructions that came with it. A Google search shows precious little about. It's the one that looks similar to an MTH Proto One bottom board.

The title on the package is RU-104 and it is also called DCRU-WD reverse unit. I think that means DC Reverse unit for Williams Diesels.

Does anyone here have the wiring hook up instructions and would they share them with me, please?

The top of the board has yellow, orange, blue, and brown wires, while the bottom of the unit has yellow, orange and blue wires. This unit is brand new in the bag.

Thanks.

How about a picture of the exact board you have?

Sorry, but I am not up to speed on posting photos. It's amazing in this day and age, I know.

Did it have silk print on the bottom? Early boards are orange center rail, brown ac ground. Blue and Yellow are motor leads. G

Yup. That's what I figured. Plus, QSI just responded to my email with a PDF of the instructions, so all is right in my train world.
