ok heres whats happening i all of a sudden have an electrical issue with these two switches on my layout. first im using O tubular and 022 switches. the red dots represent where the insulated pins are. also i use a ZW transformer. what happened is it was together and i was running trains no big deal, i could go from the outside loop to the inside loop no big deal. i started permanently wiring my layout so i decided to clean the switches and bench test them, they work fine. i reassemble this area and all of a sudden switch A when the engine goes across has sparks from the wheel and it ****es off the E unit on the engine stopping the train. 

 

whats going on? nothing is different.

the problem is happening on switch A. the engine doesnt even cross over to the other switch. also the hots and commons are in the correct places

From the diagram in the first post, looks like the pins are where they're supposed to be.

 

Badhorse, does this happen with other loco's too, or just one?

yes the pins are in the right place, and i have switched out the switches and it still stalls out on the transition,,,,,,,,phasing should be a none issue with my ZW, and the only difference was i cleaned the switches. also it doesnt matter what locomo0tive

The only thing that I can think of where cleaning the switches might be an issue is if you used steel wool on the rails, sometimes that can leave little steel fibers that can short out the hot rail with the common rails. Other than that, I would recommend rechecking the wiring again and make sure the curved or transition rails aren't somehow touching the transition rails on the other switch.

I'm assuming that there is no issue with the trains running on the "thru" tracks?

 

"...switch A when the engine goes across has sparks from the wheel and it ****es off the E unit on the engine stopping the train. "

 

Since you removed then re-installed the switches, could the weight of the engine be pressing a rail down, making contact where it was insulated before, and causing the short circuit you describe? It may not be in the switches themselves, but in an adjacent piece of track.

according to this i have the pins in the right places, you are thinking O27

If I'm not mistaken, there are two versions of 022 switches, early and late. One uses a segment in the stock rail, the other uses the rail connected to the frog. You should verify which ones you have, and they could be different.

you would be wrong, i have 022's that were made over decades and they are the same

One more thought here, maybe you could try pushing a piece of rolling stock through the transition slowly by hand, with full power on the tracks. See if and exactly where it still sparks. If it only happens with the locomotive, then it probably has something to do with the pick-up rollers as Hokie71 mentioned.

 

  Also check to make sure the weight of the locomotive isn't causing the center rail to touch the swivel rail when it passes through the transition, That does happen occasionally.

Hmmmm... interesting puzzle... I looked at the control rail fiber pins this way, inside of divergence and inside of thru 

 

when looking at it that way, excluding the center rail power division pin, the pin indicated is should be removed.

 

Inside, inside

 

022 X over on curve

 

Remove pin to correct

Try that.  Hopefully, you have only one common for all power supplies and they are phased properly.

phasing is a none issue, im using a single ZW transformer. but i will try removing the one pin, and double check my neutrals.

You should start a new post on your particular issue to get the best solution for your configuration. This post is about powered remote switches.
