Unfortunately no Jumpers there.
Heres the Schematic of the PCB which I´m using:

Make sure your wires and voltages are correct.
I don't know if it helps but there seems to be something whit voltage settings.

Check the supply voltages are present using the programmer software. Is the board powered or are you trying to power it through the PICKit3?

I tried programming in circuit and also on a bread board.
Played around with all different kinds of settings, but nothing helped.

In the Video above the guy says it should show serial no. “default_pk3” for PICkit clones, but in my case it actually shows a serial no. not sure if this makes a difference.

I spend a lot of time googling this issue and it seems like the PICkit3 causes much more issues than the Version 2 but I found no solution for my problem.

When I measure the voltage directly on the PIC, should it always show some voltage when the PICkit is connected or just during programming?

Currently I´m thinking about buying a PICkit2 or just stop wasting my time and scrap that stuff
