First zap after 5 years- you're doing well!

I still remember my first zap on Christmas lights when I was a boy. It almost brings a tear to my eyes!

Carefull cause zaps can kill! Get a 5w 120ohm resistor and put it on a test lead, attach to ground and then probe before touching. It's a bit crude and can give you a surprise but it's better than getting zapped.
