    Help! Broken coil

    Hi, my name is Damián, and i´m from Argentina. Excuse my english, but I need help with my detector´s coil and I can´t find anything in spanish.

    Yesterday in the river my Treasure Master started having problems, in my house I could see that there was water inside the coil. I opened the coil and I found a loose cable that I do not know where it goes.
    Can someone help me with this?, my idea is to seal it well with silicone or epoxy.


    Thank you very much!

    Thanks for your answer mate!, I will try to take a better picture today.
    I would like to be able to solve it, although when I try it seems to work fine, only that the cable sounds the detector.

    Regards

    From looking at photo. It looks very strange. As far as I know all the wires should have been covered in epoxy during manufacturing. It looks as if there's a wire covered in hot glue or silicone.

    Hi!, I also found the silicone strange, but that's how it was when I opened the coil

    Thank you very much for your response and attention.

    Regards!

    Oh, I'm seeing it now. You somehow pulled the layers of epoxy apart that should not be pulled apart. How in the world did you do that? I think that coil may have seen it's last day. Wait for one the the guys from White's to reply to this thread. He might have better news.

    Epoxy layers do not appear to be separated, I don´t know
    when I connect the coil works well, the only problem I have is that loose cable.
    Just in case I'll start to find out about a new coil

    I see what you saying. I have just never seen a coil apart like this one. It's just very odd.

    I have a TreasurePro here with both the 10"DD and the 9" Concentric coils. If you do get a new coil you might want to check in to the 10"DD if you are hunting in mineralized ground. The 10"DD separates better than the concentric coil too. Good luck.

    Well, if the coil is working, the wire is NOT part of the Transmit or Receive coil. That leaves the shield or ground. Because the coil is working, I'd say its not ground, so that leaves the shield.

    Your coil will "work fine" with the shield loose, but it will be prone to noise when its touched or bumped, and will be more sensitive to EMI. See if you can find anyplace that looks like the wire could connect. Remember, it had to be connected, (if it was) when the coil "sandwich" was put together.

    I'd wait for Whites response, but if it was MY coil, I'd put it back together, seal it the best I could and use it as an "emergency spare". I'd buy a new coil to replace that one.

    Hope this is helpful.

    Thank you very much, I think that's exactly what happens! It is the shield. the detector works well but is very sensitive and very noisy. I will try to find the place where to make the connection. I will rey ro repair the coil because here is difficult to get only the coil. We’ll see what it White’s says.

    Thanks again!!!

    No nothing yet. I think they have been pretty busy lately. Sorry about that.

    The loose wire in the photos must be connected to the search coil housing shielding. This is the grey/black conductive paint, painted onto the inside of the search coil bottom, which is also connected to the foil shielding in the search coil cable. Connect this loose wire to the faraday shielding inside the search coil, and /or search coil cable shielding.

    The shielding is covered with epoxy resin, so i can’t see where should i conect the loose wire. Hoy van see that point in the photos?

    That's the issue. Finding the shield connecting point after the coil is resin coated can be a challenge .... We got you to the shielding and Whites confirmed that part. I don't "see" a connecting point in the photos. You may have broken the wire off at the resin point when you opened the coil. W/O having the coil in front of me, I can't tell you where the connection point is / was.

    Good luck !!

    No problem. If I had to guess .... I'd try connecting the broken wire to the wire on the edge of the coil in photo 4227 - second set of photos. Just "wrap" it as a temporary connection and if things quiet down, you got it !! You know the connection has to be within reach of the end of the wire, so if that doesn't work, try any other point you can reach. Look at the coil surface with a magnifying glass and see if you can find a spot where the wire went thru the epoxy.

    That's all I got .... Good luck !!

    One last thought .... You could always ship the coil to Whites for repair, but with shipping and bench time, I expect you could just order a new coil and be time and money ahead.

    Again - good luck !!

    I'm surprised!!! That was tough to fix I'm sure. Did you solder it? I hope it holds up well for you. Did you order a new coil? If so, what coil did you order?

    Hi! I tried soldering it, but it was not a good idea, so I tried to physically connect it to a wire that was basically next to the hole where the wire was originally inserted (I could find it !!!). Finally after trial and error it worked perfect, finally sealed inside and out with neutral silicone.
    I tried it on the river at the weekend and I had no problems.
    I did not buy a new coil since bringing it from the United States is very difficult and I will most likely lose my money.
    Thank you very much and greetings!

    Damián
