Thanks guys, that was something I thought might work. I will try using 5,6&7 on the tortoise.

I have an electro frog turnout that does not change polarity when switched. At the moment I have no voltage "closed". I can switch to "thrown" & locos pass through nicely. Hit the "close" & the frog has no power. Tried switching tags 2&3 around on the tortoise and it just reverses the problem (no voltage on throw). I have 32 tortoise motors on the layout & all OK. I have continuity from tortoise tag 4 to the actual frog. Also, no shorts occur. Could this be a faulty tortoise motor?

AS a matter of fact David, after finding 11 frogs were wrongly polarized by using the multi meter, I started trying to correct just the one. That could have caused the short circuit. I am away at the moment but will attend to ALL the turnouts on my return. Thankyou. Allan (Halgate 64)

All the turnouts were used perfectly on my previous layout prior to a house move, they are peco electrofrog, they have all been altered and plastic joiners connect the frog rails. All the tortoises were used on my previous layout and were also perfect plus the wiring is the same (I use chocolate boxes so I do not have to unsolder the wires from the tortoise. I dont believe for a minute that the problem is with the tortoise. BTW, its the same with 11 other turnouts. Going out there shortly to go over EVERYTHING again. You guys are scratching your heads and so am I as I fully understand the workings (although not as fully as I thought, obviously). I have not been to the train shed in the garden for 24 hrs due to having to sleep then go to work. Haha, not had much sleep I can tell you.

Have tried switching the input wires over, result was a short circuit. Another common (no pun intended) denominator is that the problem turnouts all had the motor power leads 1 & 8 switched over to coincide with the correct action of the command on the throttle (throw or close). I will concentrate on that being the problem for the time being as I have checked all the wiring (input wires to the frog 2 & 3) and they are correctly wired. Thanks for all the advise guys, I appreciate your thoughts. Allan

Hi, I agree with you and have tried that but regardless, the polarity of the frog changes also, so it's always different. I even tried changing the power feeds to the frog (connectors 2 & 3) but of course that just creates a short circuit. These are tortoises that I have had operating perfectly on a previous layout. Cheers, Allan

Hello, I'm new to RMWeb. I am building a DCC railway using Tortoise motors and electrofrog turnouts. The turnouts Open or Throw with each command correctly, however the polarity of the frog changes to the contrary position. Oddly, one turnout of 12 so far installed, is installed under the boards facing a different direction to the other 11 and it is the only one with the polarity in the right place. Any ideas please? I operate a Digitrax system assisted by DS64s if that's any help.
