I must have been due, it's been quite a while. On a call out this week end I still had the back of a condenser opened up after getting it running. I had my arm inside feeling how hot the compessor was. Little 83 yr old lady popped out of the door and asked me something. I flinched and layed my arm ever so perfectly across the duel cap.
After removing my arm I looked down and of course the ground was wet from a brief rain. Figures!!
