   You need to compare the resistance between the two
pins and the meter leads connected together directly,
on the lowest Ohm scale that the meter has, like X 1.
   You should have around 50 or more Ohms, then press the
PTT bar/button/key does it change?
It should if the MIC is switched, which isn't always
done, as it can cause a big kerchunk on the air if the
mic switch doesn't occur before the PTT switch.
   (it must be made that way to work reliably)

> It shorts even without the PTT bar pushed in.

   Many times the MIC is not switched, that eliminates
the kerchunk problem and also allows the MIC to work
with VOX.
