Contibute to repair Carprog Hello, My contribution for this helpful Thread! After ask that I have problems with my carprog "pin8 have short to power" I put hand on it and resolve this in the best way!. So the problem is I bay a CLONE-FROM-CLONE-FROM-CLONE!!! With vary bad pcb layer On the micro and in all pcb. First to resolve my pin 8 problem whose the missing line on button pcb side and the hole whose not connected! Restore all and pin 8 whose GONE GONE. Second not read MCU Motorola or I2C or 95...., change all 74HC125D to 74HCT125M put a new cristal and condensators And all missing resistors on my pictures and make the new connection on the power socket so that I have more space to close the carprog housing without bending the pcb. And in the last modification is that isolate type! Is necessary IMPORTANT!, carprog have a separate GND and when put The PCB back in the housing sometimes have problems in read some MCU or eeproms! So I find out that the pcb in one side from the regulators make connection to the housing and make in The same time short to the another side from the PCB! Final Result Without put double 74HC125M (8x) to read I2C or 95 or MCU without or with external power My carprog read all without external power.
