Ed, Before you unsolder the throw bar file two small notches through the copper cladding on each side just inside of the points a little that should isolate them from each other unless you have solder contacting the bottom of the throw bar. I went through this same thing before. Spent most of a day looking for the short at a train show.

Hey Ed, I've had a lot of good suggestions. I wish everyone would answer on list so others would benefit from their wisdom. The top to bottom short had not occurred to me. You're not the first to mention it. I think it is really the only possibility left. There is no short anywhere else. I've electrically isolated this turnout. In fact, I've cut all the feeder wires to the rest of the track. It all rings dead with no shorts. You're right about being able to use the points shorted, but only if I switched them for track power and removed all the copper from under the stock rails. I don't want to do that. I guess I'm going to have to unsolder the throw bar. I've run out of options. Thanks again to all.

Is the rest of the copper still on as shown in the photo? One possibility is that there is a short between the top side of the throw bar and the bottom side -- assuming, of course, the bottom side still has all the copper on it. Might a sliver of solder or something else be connecting the top side with the bottom side? Perhaps unsolder the throwbar and remove copper in the center area of the bottom side if some kind of mystery short circuit between top side and bottom side exists. Another possibility is that the top side of the throw bar is touching the bottom of the stock rail -- on both stock rails -- at the same time. And, if there is a short circuit somewhere else (away from this specific turnout), then that short will appear as a short between your points. But the short is not within this turnout at all -- it just appears to be. > The stock rails are dead. Have you checked the stock rails for a short circuit? The photo shows some stock rails connected to other trackage via a rail joiner. > If I use an > ohm meter to check continuity, the two point rails are shorted. Maybe so, but you can still run the trains through the switch if the stock rails are not shorted to each other. Granted, this is not good. > I can > slightly bend the points downward so they make no contact with the > stock rails...the points are still shorted. But is the top side of the throw bar making contact with the bottom of the stock rails? Maybe a small piece of wire/solder/etc. is in there somewhere even though they appear not to touch each other. Can you slide a thin piece of paper between the stock rails and the throwbar? > > Can anyone offer a suggestion before I rip out this turnout and trash > it. First suggestion is to NOT rip out the turnout until AFTER you determine what the problem is. This is a solvable problem and not worth trashing the turnout over. Second suggestion: How about slicing a strip of topside copper off the throw bar in the area between the open point and the adjacent stock rail. See if that improves the situation. Third suggestion: Buy Dick Karnes an airplane ticket and he will solve the problem for you if nothing else works. > I'm really stumped on this one. Good puzzle. Not sure if I helped, but it will be interesting to find out. > Ed Kozlowsky > Sanford, Maine Ed Loizeaux California [Non-text portions of this message have been removed] [Non-text portions of this message have been removed] Yahoo!
