Minelab CTX 3030 WM-10 repair

My Minelab CTX 3030 WM-10 unit has been fine for 2 years, it has not given me a sign of trouble, the battery life has been good, it held a charge….then all of a sudden nothing…it went dead !
Not wanting to spend £180 on a new unit I decided to have a look and try to find out what was wrong, perhaps a wire had come loose.


The WM-10 cordless headphone unit was opened by removing the 4 screws to expose the board and other components….Now be very careful at this stage as things are pretty tight in there and the battery wires have a specific path from the battery to the board.

How to fix the WM-10 cordless headphone unit

Dis connect the battery carefully, taking care not to damage the white connector back as you may need this when you buy a new battery. In my case I cut the new connector block off and used my wiring and block as the new one was the wrong size.


Carefully take the felt pad from the old battery and stick it to your new one, and assemble, making sure that the battery wires fit in the exact position they came out.
I got my battery from E BAY for £7.00, it is a higher capacity than the Minelab one and should last for many more sessions, possibly out of an RC helicopter or Drone.


Take care Lipo Batterys can be dangerous

As always take this repair on at your own risk, battery’s can be dangerous, charge the unit up for 3 hours during the day when you are around and never leave it on all night.

I accept no responsibility if it all goes wrong, all I can say is it worked for me and saved a fortune.


Here is a video showing how simple the operation was.
