btw,
on another forum there was a guy with a fence-charger.
he "tested" it with a fluke87 and killed it - no surprise really.
if you can kick a cow over a mile from the device via damp soil and a fence the energy must be pretty nasty.
what was funny, he then "tested" it with a uni-t mini meter and it displayed 3KV!!!!
i dont know if that was the true voltage but it didnt kill the meter :wtf:

Once I checked TV tube with unit like Harbor Freight
And it says 1300 DC without damage

I thought these resistors were internal to the IC.
Which ones are you referring to?
stj:
i'm saying - CHECK EVERYTHING.

They are. Your 48 ohm resistors is another tell tail that the control IC has seen better days.

Hmmm. The chances of reviving the meter are going down by the minute...
Its also very difficult to source this IC. It looks like that although only one
diode (from the two in the switching package) was zapped, both FC1 & FC4
were damaged inside the IC. After installing external resistors to ground,
the modes are ok, but mV, V and Ohms do not work. V mode flashes like it
changes every half a second from one mode back to V, mV does the same
but extremely fast and displays OL and Ohms does not measure anything.
