Explorer SE Failure to Switch On Fix.

Metal Detector Model = Minelab Explorer SE .
Fault = The Detector intermittently will not switch on or will not switch on at all.
Cure = Replace Electrolytic Capacitor C605 on the power supply board.
This power supply board is a small plug in circuit board inside the detector , it is very easy to remove.
The capacitor is a 2200 Uf Electrolytic , Voltage rating is 16 volts and is a 105 degrees type.
So if cleaning your battery connectors fails to get your dead SE working try replacing this capacitor.

I have not opened an Explorer 2 up , so i can't say for sure. I would have thought they have similar power boards , it takes a few minutes to open the detector control box.
The Capacitor that fails is a known not so good quality brand capacitor made by Samwha. The Capacitor is from the WB Series of Samwha Capacitors which had a high failure rate.

The Se Pro will have a similar power board to the SE . I would guess many of the faults on the these detectors are on the power board.

Reference.....Here are pics of the board from an Explorer II



...CTX, DP-Pulse, and over the years, 22 other detectors...

That big capacitor over to the top right near the white connector is a prime suspect if your machine powers off on its own , fails to starts or goes "cuckoo" in any way shape or form ... I would not rule out any other of the caps on the same board either..

Where does one purchase a new capacitor? And what brand do you suggest? Does the capacitor just plug in to the board?

Tony, as an example , here's a link to one of the many equivalent ones available on line from ebay usa.
http://www.ebay.com/itm/5PCS-2200UF-2200mfd-16V-Electrolytic-Capacitor-105-degrees-USA-FREE-SHIPPING-/270896099958?hash=item3f12aa7276:g:6EkAAOSw1WJZOEJa

The capacitor that's needs to be replaced needs to be carefully removed, usually done by de-soldering it from the board then soldering in the new one.
In some instances this capacitor and other components, have also been bound to the pcb with hot glue , so you may need to firstly melt/ remove the hot glue from the capacitor.
