I have a left & right hand O36 swithc. LAst year they ran fine on track power on the carpet polar express. Put them into the layout I was building yesterday, wired together so that one would cause the other to throw, and power supplied from an aux source.

 

Turned on the transformer (CW80), brought track power up to 80% and the green light started blinking. Secured all power. Verified connections, Disconnected aux power to switches, applied track power, green light steady on (good).

 

Used a boxcar to check derailing feature, no response with track power (jumper(s) reinstalled) from either switch from either spur.

 

I've checked the internal 2ohm(1/4W) Resistor/fuse on both, they're good

 

Suggestions?

Read attached. A bad production batch from a couple of years ago had the wires reversed.

 

Only happens on aux power.

 

I have also had no luck when wiring them together for a simultaneous throw. gave up and use RTE off an SC-2 using one terminal position for each switch. Didn't feel like troubleshooting anymore after a few days of multiple configurations.

So I followed Gunrunner John's advice, bench tested each with track power separately, with the track power jumper where it should be, and neither worked. Control wires between the two disconnected, so that each switch was on it's own.

 

While power was applied, took voltages with a Fluke 87. All center rails read 17.6Vac compared to the outer rail, which equaled the piece of fastrack that was being used to apply power. I also moved the power track to each of the three "ends", with no luck. Regardless of switch, there is no reaction when a piece of rolling stock (yes, with metal wheels) approaches the points and they're not in the correct orientation

 

I also took voltage from center rail to isolated "inner" rail where the out/thru meet, that are supposed to allow the anit-derail to work, and they were .5Vac less than the difference across the rest of the switch

 

I think that I did have a miswired set, since they worked fine off track power the last two Christmases, but when I used Aux power, then ran track power up to max, burnt something out.

 

I'll see about aux power "backwards", and if that doesn't work see if my LHS will help. If not, the motors are coming out to make them manuals

John it moves freely 100% no issues

It's 100% electrical

I was saying that i'd yank the motor to allow it to function as a manual, and therefore easier for the pilot truck of the 1225 PE to operate it
