Problem with ZW-C handles A & B Working Together

I would check the gearing on the A/B handles and make sure that something did not slip out of alignment. Should be a somewhat easy fix.

This also happens with cab2.

When changing out my ZWC last night to a ZWL I accidently had the hot side of the D side come off a connector on one of the DPDT switches in my little box that I use to route power to my block sections. I was moving controls to make room for the ZWL so prior to pulling the ZWC offline I powered up and the disconnected channel D was showing 9 volts so I went looking and found the issue. Maybe something similar?

I hope this helps.

I have nothing attached D.This happens also with all the bricks off except the one attached to A.

Have you done the reset procedure listed in the manual?

I did not see a reset only a reprogram  which I did. 

Check wiring, sounds like you have the two outputs shorted together.

I removed 1 of 2 wires from B and the ZW acted correctly.Put it back and the problem reoccurred .one of my switches that I just hooked up does not light when I remove the plug.the sc2 that it is attached to I removed the ground from the switch to remove the sc2 from the system,powered down. This was happening with the ZW so I disconnected the SC2 to diagnose the problem,it did not help.Only taking wire off of B did it.

You do realize that there is a ground connection to channel 1 of the SC2 that many of us remove to make that channel match all the other channels, right?  Maybe that ground is screwing things up?

I pulled the ground off the sc2 to cut the power.Grund on the first switch position.ths failed with the SC2 powered or nt.I added an acc.(oil well) and a switch to this sc2. This is the switch which will not light unless the plug s in. 

I think I'm getting lost in the footwork.

I'd start by testing the transformer by itself with loads on each of the channel, make sure that's all working before proceeding.

All the outputs work with the 1 wire not attached to B. I have 2 wires attached to B. One attached works,both do not.

Well, it would seem that there is some sort of short or feedback between them when the circuit in question is connected.  The trick is to figure out where.  Without a diagram of what you're doing, it's hard to suggest exactly where to look.

I was going to trace the circuit. It is weird since it was working then stopped working without apparently any intervention. How would I get a feedback?

Thank you,

With a problem like this, I just keep disconnecting individual pieces until I find what is causing the failure.  Like I said, without knowing exactly what the whole wiring scheme looks like, it's difficult to offer a specific suggestion.

I traced the problem to the plug on 1switch that supplies the aug power.Unplugged and then reinserted and it worked. Any ideas? The switches are Lionel 022 031.

Aux not Aug per previous post

None except that I'd take a look under the cover and see if something is amiss.  I suspect the contact was making and connecting the track power to the aux power.

What I did not mention that the plug was partially in.

There you go!   If the internal contacts can connect and the barrel is still connected, you have the two connected together.

FWIW, those tapered plugs are pretty infamous for working themselves out and doing exactly that.
