Default Peco frog problem

Well this is a new one I've not seen before. One side of the frog "V" is live and the other side dead. I think they are welded together underneath so will have to take it up and see if I can repair it. Anyone else come across this before?

That's correct for an Insulated frog point. One Vee direction live the other dead.
On an Electrofrog point the two Vee rails are the same polarity depending on the point blades or frog switching position.
So if you're using electrofrogs simply bond the two Vee rails together somehow rather than lift a ballasted point (Assuming its ballasted?).

Yes it is electrofrog. Not ballasted yet as I've only just laid it a few weeks ago and now only running trains over it. I suppose I could solder a wire link on top as this would be to the outside of the rails, and in the end might be more accessible than underneath if I do lift it.

Annoying though at it must have been like that from new but can't remember where I bought it from. I just wondered if anyone else come across it.

The two vee rails are actually connected by wires underneath, and if one of these becomes dislodged you can have the problem you describe. Happened to me on one of mine and to resolve it I needed an extra wire soldering on the dead side to connect to the polarity switch on the Tortoise point motor.

Thanks Robert. Just had another look and there isn't a lot of room to get in with my iron, and I could well damage the IRJs and/or plastic sleepers so looks like I will have to lift it. Luckily its right at the front of the layout. Gone off Peco.

I wouldn't blame the Peco make, its likely the 4lb club hammer you use to put the track pins in with may have something to do with it....

Your just unlucky. Only time I had a problem with a Peco point is when I trod on one.

It's a bit of a weakness with these points especially if you pull them up and re-use them. I always solder a robust frog wire on mine before laying and do not rely on the somewhat flimsy one as supplied.

And after past experiences, I now check continuity on the frog with a meter before relaying points.

The only new point I used on one layout was a Insulfrog Double Slip and then went dead on one of the exit routes after it had been positioned on the layout.

Yes but how do you do it without damaging the plastic. The spaces are awfully small to stick a soldering iron into!
