If the Multimeter reads +5V that is WRONG!

The signal is 50% Dutycycle changing from +5V to 0V. Any RMS multimeter should show a lower value. If you say the voltage reads 5V I suspect your WDT signal is continuously high. Perhaps some problems with the way you connected the RC circuit to the 555 Timer?

Cheers,

Jasper.
