Have a Tesoro Vaquero. Worked absolutely flawlessly for two years (and it's a great machine), then suddenly this morning, after assembling it fully and correctly, I turn it on and (after the initial "battery test" beeps) it blares out a loud continuous tone that can't be stopped (aside from turning off the detector, obviously). No adjustments to any knobs have any effect on the sound. The battery is brand new. I am not near any metal. Anyone have a clue as to what is causing this?
I suspect the problem might not be with the "brain" of the machine, but instead with the coil (the standard 9x8 coil that came with it). If my memory serves me correctly, if a person attempts to turn on any Vaquero main until without having a coil plugged into it, the machine will emit this same loud continuous tone. The tone will stop once a coil is plugged in. Is this correct? My problem is that I have no other Tesoro machines and no other Tesoro coils to test out this diagnosis. I now get the same continuous blaring tone whether or not I have the coil plugged in. It's as if the brain is not noticing the fact that the coil is even there, indicating perhaps that the coil (or its cable) is broken somehow.
Not sure why this happened -- perhaps the cable got crimped and the wire broke inside? I don't notice any obvious flaws in the coil or its cable, but one never knows.
My plan is to just buy another Tesoro coil somewhere, and plug that new one into the same main Vaquero main unit, and perhaps that will solve the problem. Or perhaps I'm being a fool by buying a new coil to go with a broken detector! That's why I'm making this post -- to try to figure out if the problem is with the "brain," or instead with the coil.
Anybody have a Tesoro? If you simply switched on the main unit without having a coil plugged in, what happens? Does it emit a loud continuous tone? Or does it remain silent? I wish I could test this out myself, but with just the one machine, I have no way to do that. And now that Tesoro is out of business, I can't send it back for repairs, and no one there answers the phone.
Any help or suggestions would be most appreciated. Thanks!
