After wiring / installing my new ice cap 660 w/ 3 5 foot vho's into my canopy, I notice one of my pumps wasn' running. Of course I grabbed the pump in one hand, and tried unplugging/replugging the cord with the other hand. Needless to say, got the $h!t knocked ot of me. I have been hit by 110 many times, this was the worst, it threw me about 3-4 feet! But after I collected my self, said a few choice words, etc.... Got to plug my new lights in, so all in all it was a good night. Just thought I would try and provide a good laugh for someone this morning!
