PIC12f683 GPIO.0 Trouble

[Larryd]

Louie,
I just tested, it is 4.88 V.

Also don't know if this helps but once the 12F683 goes into the over heating mode,
I removed connections on pins 2 - 7 and it still got hotter till I disconnected power.

Thanks
Larryd

Is your 5V supply really 5V? Does it stay at 5V when the relay is activated / not activated?

Sounds like you have blown up the chip. Check what voltage is being fed into GPIO.4.
