AAA Precision Turntable Wiring Diagram

Chris, I have one on my S gauge layout. I posted some pictures below. The back of the small control panel is almost inaccessible, it was put in prior to the final layout structure assembly so I cannot get a camera and my hand in the space at the same time to hold the camera and release the shutter. I will see if I can get a better picture later today.

The pink and tan wires are the track power, the gray jacket cable from the top connects to the bearing plate terminal block and the one from the left is from the 12VDC power supply.

Here are the best pictures I can get. They should be good if blown up a little.

Mine was purchased in early 2016. We requested their super detail treatment, it was ok but the layout builder had to further detail it. The pit rail was replaced with Code 125 NS rail for better function and appearance. The TT has worked w/o issue since the layout was completed in 11/2016. I use it frequently. The optical alignment system worked great, the TT can be set to stop at any angular interval.

So, if I'm looking at your pictures correctly, what I have drawn below is what you have, Yes?
What are the 2 red wires in your second picture? Looks like they go to the same terminal.

Hopefully one last request,
Any chance you could possibly get the part numbers off those 2 switches?

Thank you very much for your help.
Chris

The incoming 12VDC is black/red. The second pair of black/red wires runs from the switch to the terminals on the bearing plate.

I will see what I can do. The only access to the rear of the control panel is two small oval holes in the layout structure. There is not enough slack in the power supply cable to pull the panel out the front of the fascia even if I can remove the rear screws. The pushbutton and switch came with the turntable.

If it's of any help, the rotary switch appears to be a DPDT center OFF and could be spring loaded return to off.  @AmFlyer would know for sure.

Here's an option:

Maybe an electrically similar Toggle switch would also work.

The push button looks like a momentary SPDT, with only one function utilized, guessing it's the NO side.

The switches current rating is an unknown to me, but may be derived from the documentation or on the power supply label.

@Jayhawk500  My apologies if this is already obvious to you.

I cannot physically get my iPhone into the space to get a straight down picture of the switches part numbers.

I am attaching a sloppily drawn wiring diagram of the entire TT system. The 18VAC supply shown is from Channel D of ZW-L #2 on the power cart. The 12VDC is from a DC power supply. Only two of the three terminals on the pushbutton are used.

SteveH is correct. The TT direction switch is a DPDT Center OFF. It is not a spring return to OFF. This is visible in the picture, the switch is set to CCW.

The pushbutton, when pushed, completes a circuit that increases the speed of rotation and bypasses the auto stop function. Releasing the pushbutton allows it to stop at the desired track.

Thanks Tom

Thanks Steve, I'll take a look!
The screen shot is great, But a link would be awesome.

Never Mind, got some ordered, Thanks.

Yep, your drawning is the same as mine. Thank you again for all the help! Much Appreciated!
I know someone on this site would know something.
