Excalibur reverse polarity

[Tippy]

Hi Folks,

Was using the Excal, and noticed it was down on batteries. My kids replaced the rechargeable batteries, but had reversed all the batteries.....giving me reverse polarity....ouch !! Excal will now not give me any kind of tone when I turn on....is there a fuse of some kind on the circuit board?

This is an Excalibur 1st generation(blue in color, 10' coil), and out of warranty.

Saw that Minelab has a 30+ day turn around. Been fiddling with electronics for 20+ years, so I am not against opening the excal up....just looking for some advanced info.

Thankyou !!

Dont know about Excalibur's but explorers dint have diod to save circuit boards if polarity is changed, if this is the case with excal you have problem, but before open and check what is the situation. logically thinking if its easy mix polarity should be some fuse. good luck
