Hi Hector,

What i really need is the schematic for the coil cord connector, as I accidently destroyed it. I didnt bother to notice the setup.

The coil itself does appear to be missing some shielding on the larger outer coil. I basically just took this apart to see what all the hoopla was about inside. If it dont work I throw it away. So I may be making a donation to Homefires day of the Dead.

Thanks for the reply.

What do you mean by destroyed?
I can give you the color codes since I think the 7012 is the same but a bit more powerful model.
I really would like to find out the difference.
I bet you have one or more broken pots and or a bad coil shield connection.
Once you get the top portion fixed, you can check the coil for reliability.
On the small coil, the connection under the tape needs to be improved.(shield)
An ohms check should read 0 from the foil (large coil) and carbon coating(small) to the little board that the wires connect to(center wires) to the connector pin at the end of the plug.
Show a pic or 2 of where you're at and I'll help you get it going.

I got sidetracked, sorry for the late reply.

The connector is a 5 pin (midi) type not the same as the standard 5 pin you see on my BH detector.

This is a 15 khz machine, so worth taking another look at it. Im just looking to make it work, and test to see if I can use it for fine or small gold.

The outer coil rings high and some shielding was missing. I will have to check circuit board for anything burnt. But Im sure a little shielding and fixing the connector should work.

I was considering a (pull behind) coil for this unit, for meteorite hunting. But winding a coil is easy, making it work is another thing.

Thanks for the good info.

Hi Hector, we posted at the same time.

The connector that goes into the control box from the coil was one problem. I got careless and didnt write down what wire went to which pin. The connector was all twisted inside and probably the problem anyway. The pin figuration would help greatly.

I have only had the control box open once. I was considering soldering the wires directly to circuit board. But wanted to add a second homemade coil later. So I havent done that yet. I had to open up coil for color code on wires, and to ring it out properly.

The coil was easily opened by gently grinding the sides off the coil itself. Inside I noticed the outer coil (foil wrapped) was missing shielding. I was getting a .7 on ohms/continuity. So need to get that down to zero, get the moisture out, and seal up the coil again.

Since the detector would briefly try to work, just finding which wire goes where, and adding shielding to the coil should work.

I did way too much to this machine. But felt better about taking the time to open it up and make sure I had checked it out. It is a low end machine, but would make a nice machine practice machine as it has the TR modes and manual ground balance. My current machine is turn on and go.

The wire from the little board may have shorts. Im considering replacing that wire from the coil head to the control box.

You mention shielding on the small coil connection under tape. I dont know what to use for shielding. Im used to mylar premade inserts for windings and such.

Give me a few minutes and I wil post pics. Thanks.

Okay here is some pics.

hector I didnt put a pic of the end of the coil wire, its just five wires. Think I should replace the wire from the coil to the control box too.

WOW!
Must be like the Canon Vixia/Legria...same unit, different name.
That's the EXACT same unit! Shocked
You can use the color coding from inside the box to match em back up or I can tell you what color goes to what pin.

If some of the Foil is missing on the sheild just put some more around it! Plain old Cheepo aluminum foil from the dollar store is so thin you can about read through it. LOL!

Well, When did you figure out the Coil wires?  Did it work?

Well coil is now at .001 ohms. Getting ready to solder the 5 pin. Needed to look at pics of connector one more time. My new coil I bought can wait, I want to see this detector work. Probably should take some pics of repairs also.

As I sit here writting this, its very late. I just changed for a potato chip eating contest, you cant eat just one. So the 5 pin will wait till the morning. Just as soon as I finnish this last chip.

Sorry guys about dragging my feet. I have a pleasant distraction in the form of a new 10 inch coil. Im very close to getting the 5 pin done.
