Before installing the next batch of turnouts I decided I would test them before the install. Unfortunately I found a large number (75%) all seem to have high resistance on them that is causing false detection..
I have enlisted the help of the folk on the Rail Wire forum to see if we can figure our why..

Here is a picture of one of the problem turnouts..
As you can see from the picture, the gaps in the ties are large.. So it is a bit odd I'm having these issues.
Lets see what I can find out the the help of the global railroading fraternity!..
Thanks.. I will keep this post updated with what we find!
That's a good one, it could be the QLD humidity in the wooden ties, but I think not!
ReplyDeleteIt could be some capacitive coupling between the rails, but it is strange that the BDL is that sensitive.
I have a pretty good fluke meter that I can drop round if you want that does capacitance and it has a megger feature.
