Absolutely - I removed the ties from the lead tracks to see if it would make a difference - it did not. I then checked the bridge rails against the pit wall and discovered that they were lower than the ring where the lead tracks would rest. It's too late now, because I have already ground out small slots to lower the lead tracks to match the bridge rails - I was just wondering if anyone else had this issue and how they solved it. So what I did was cut slots in the pit rim, slightly filed down the tops of the lead tracks, sanded the bottoms of ties between the pit and the roundhouse and now I plan to fill in any gaps in the pit with gray putty. All is good & trains move smoothly across gap - I just wish it was a little easier! Hank
Code 83 should be code 83. You just have the rails on the pit wall right ?
Have another question - my bridge rails are lower than the pit edge where the service tracks attach - I had to Dremel out a slot for my rails to be lowered so they meet the height of the bridge rails. I checked the bridge rails with a caliper and they are code 83 as are my service rails. I did have to sand down the bottom of the ties to lower the track - Has anyone else had this problem or is there an adjustment - although it might be too late now, I have already made slots and attached the track - just for future reference. -thanks- Hank

I have the pre-DCC version RTR and it is just two buttons for rotation, dont use the programing feature.
While most of the electronics are in the bridge, there has to be something int he control box besides the buttons and the LED display, as there are not enough wires coming out to directly address the number of controls present in the box - it's encoded somehow. I suspect whatever chip is int he control box is a bit more than just a logic chip, more like a small micro to endocde using some sort of serial protocol, meaning without that workign component, you would have a very hard time duplicating the box because the it's not likely the protocol used is freely available.
It may be possible to use the enhanced interface they sell to connect your own sort of a DIY control box though. But a replacement control box might be the cheaper solution.

This brings up something else. If the box was to totally fail, could you remake the controls with a couple of momentary switches?
Baron987, Clean the prongs under the bridge and rings on the bottom of the bridge with alcohol and a Q-Tip. If that doesn't work, make sure the prongs did not get bent.
The first few months I had mine I had to clean those items constantly which makes me wonder if some sort of film from the manufacturing process was involved. After cleaning it about four times in a short period of time it seems to be fine without the regular wipe.

Well, that sure sounds a lot like my problem back in 2018. Once I got the turntable working again, it was as if the control box had been in sleep mode. Give it another try and check that all connections are secure.

My controller is dark - Everything worked for the last 6 months, lined up perfectly with the roundhouse - now nothing - if I play using my voltmeter probes touching the brushes, I was able to get an E6 message on the controller - that tells me my cable from the controller to the turntable is not bad. The track power is fine. I am using DC for now, but if I can't figure this out, why upgrade? Any ideas?
selector Rich, my bet would be on a bad connection, and if I had to put my money down on one slot, it would be the one reading, "Bus end feeder connection." Unless you can tell me that the other end was tight, didn't shift when probed, and that if you probed the wires only at that end they showed voltage?

To put some closure on my issue with the turntable control box, I decided to take another look at the whole situation.
Now recall that I could not get power into the control box, and the only way to do so was when I touched the probes of my voltmeter to the set screws that hold down the two power wires on the control box. Of course that is nonsense, and I am all but certain that it was mere coincidence that it lit up the Power light on the control box.
Even then, however, I could not get the motor drive to work on the turntable until I move the two bridge track wires to a different power district bus. So, this morning, I moved the two bridge track wires back to the original bus, and it worked.
So, I can only conclude that the control box circuitry initially malfunctioned, or else something else weird happened like the control box going into and out of sleep mode. LOL.
All very weird.
I am thankful you got yours to work. We have one at the club that will just spin and spin and spin- locked into the program mode. Walthers did have probems with these.
By the way, good old Walthers never returned my phone call which I made to them yesterday morning at 9 AM. I got Tech Support's voicemail, so I left a detailed message explaining my problem. I wasn't looking for a free replacement control box or any warranty service, not after 14 years. But, I sure would have appreciated the courtesy of a return phone call and maybe some advice about the nature of the problem. I recall a time when Walthers seemed to care about its loyal long time customers.
floridaflyer Rich, do you have output power from the original PSX-AR that would lead to the turntable ?

Rich, would be interesting to see the root cause of the original problem, but that may not be worthwhile pursuing.
I just wired in my Walther's 90' Ready Built tuntable. Since it was the first version and I run DCC, I added a DCC Specialties PSX-AR to the turntable track. My turntable runs just fine and I can now run my engines on and off the turntable with no issues.
Walthers was selling an upgraded controller for $100 (I think), but for $55 this is great!

OK, I got it working, but my explanation of what I did will seem ridiculous.
I followed the instructions to the letter, still nothing. I knew that I had power from the DCC bus to the two input ports on the control box, but no power in the control box, no red LED lit up. At that point, I touched the probes from the voltmeter on the screws that hold the wires securely down into the two input ports. The red LED Power light came on!
But I still could not operate the turntable. So, I moved the two bridge rail power wires from one bus to another bus, and now everything is working. The bus that I initiallly connected to was the bus for the power district in which the turntable is located. It is controlled by a PSX circuit breaker. The bus that I switched the two bridge rail power wires to is for a different power district, also controlled by a separate PSX circuit breaker, that contains my double main line.
I don't know what to say. I cannot explain how and why I got the turntable working, but I did.
In my case, with the 90'er of the same 'built-up' Walthers turntable, the indexable one, The well's metal rings must be very clean and free of corrosion. Same for the wipers under the bridge's central cylinder. Electrical contact cleaner may help...IF that is part of the problem here. Even a plain pencil eraser, if you can use it effectively, does a pretty good job on metal wipers for electrical contact. (Worked for me for decades with the contacts on cordless phones.)
I have a suitable, in-voltage/amperage-range wall wart that powers the mechanism and indexing only...via the flat buttoned panel. I seem to remember that both wires go to the mechanism's cover directly from the wall. The paddle has its own bus for controlling the mechanism and is mounted on the fascia or whatever.
There are two wires that go from the mechanism cover up to the pit's well, but you should never need to deal with those...they are internal and hidden. The only other wires come directly from your bus wires and also terminate at the side of the mechanism cover.
Once you can operate the mechanism, you would want to do a reset and do your presets all over again...the indexing stops. A good way to get it right if you have to clean the turntable, which I did about once a month, is to alway have the control 'shack' that the operator uses at the close end of the lead. IOW, before you clean, or take an engine onto the TT to turn or to place into a roundhouse nearby, make sure the operator's booth is closest to the edge of the lead where it meets the pit. Lift the bridge, fiddle, clean, detail, weather...you name it, and when you want to restore it already indexed correctly, line up the rails with the lead, but with the booth also at that end as before. This always worked for me.
Yes, the bridge rail connections go to the DCC bus., They don't pass through the control circuit in any way, other than the split ring pickup that gets the power to the moving bridge tracks (with the dead spot gap in the split at the points where it is marked to not put any stall tracks). The other power leads are the one that actually run the circuit and power the motor.
So if you've hooked it up that way, it is correct, and if the voltage at the power input with everything connected is still above the minimum, it should run. If it says AC or DC, then there is at least a dioode if not a bridge rectified immediately inside. If you are using DC power, perhaps try switching the order of the power wires, if the input protection is a simple single diode, it would mean that it does indeed matter which way a DC power supply is connected. If using AC, it would never matter.
richhotrainWhen the instructions say, B1 and B2 connect to the rail supply, does this mean to connect B1 and B2 to the DCC bus?
I don't have one, but what else would supply the rails, if not the bus?
