I have designed a very simple probe with a resistor and LED and an earth lead. This is designed so I can push the tiny probe into a crimp and if there is voltage the LED will light.
When stimulating the 50V in the Lab this works (It works when I use a Teknikit Console to produce 50V,), but have now discovered that when I put the earth lead to an actual earth does not work.

Hi all,
I have designed a very simple probe with a resistor and LED and an earth lead. This is designed so I can push the tiny probe into a crimp and if there is voltage the LED will light.
When stimulating the 50V in the Lab this works (It works when I use a Teknikit Console to produce 50V,), but have now discovered that when I put the earth lead to an actual earth does not work.
Can anyone help.
