ok, i've tested it now, it finds an AN589 programmer and says no pic found, could it be that i've killed my pic?

xD yes you was right and the second problem i was now having is that the same was burned through because of that. now it works as it should, but now i've the problem that p18 couldnt identify the pic18f452 there stays only 18f???

Hi, after some hours of troubleshooting and corrections on my selfmade pcb i have now a problem with the voltage on MCLR# I've not much knowledge in electronics but i hope you can help me. All Parts for the PIC Burner i've got at the local Seegor electronics store but they didn't have BC337-16 so they gave me the BC337-40. i setted the voltage on J2 to 12.6V and when turning VPP on i get only ~7.7V on MCLR# and i think it is because of the wron BC337.
