Hi all i have managed to wire my detector battery up wrong (positive to negative , negative to positive ).
It is 2200d , now that i have wired it up correctly it does not turn on.
Have i killed it ? is it going to be expensive to fix?
Thanks

Hi Zacc
There's an electronic fuse that may have gone,it protects for overcurrent.A diode is across the battery supply to protect against rev polarity.
Try woodies site here and scroll to the bottom(its under sd2100 but specifies 2200 as well)

Apparently you can bypass this as a temp measure if needed there is a youtube video for doing this.

Gday zacc

My advice would be to take it to your local minelab dealer, or send it to minelab yourself, tinkering with things you dont know about will usually result in further damage, at least when you get it back from them you will know that its has had a good checkup and should be good to go for some time.

Its hard to say what needs doing to it at this point but you can call minelab service department on a freecall number (1800637786) speak to a technician and they should be able to give you a ball park figure on the repair costs.

cheers
