Hi, i buy original TL866II plus with almost all adapters from you. I have problem that i cant read PIC18F452-i/pt.I select microchip pic18f452 (dip40) in program and select ICSP port (ICSP_VCC Enable) and soldered wires to same chip but in TQFP package. And try to read it but it start to read it and when it almost finish reading it give me error: overcurrent protection! external short or IV reversed... Can you please help me how to connect and read that chip please, if i did somening wrong.
