"WITH THE DAMN THING UNPLUGED. EVEN THEN USE A WOOD STICK THATS DRY. YOU CAN GET KNOCKED ON YOU ASS FROM THE CAP IN THE CIRCUIT. "
What SanClem is referring to is the capacitor in the ballast. Just because the light is unplugged does not mean it is not 'hot'! To build up enough power to ignite a HID bulb, the system first charges a capacitor which is similar to a battery but works on a different principle. It has a long, coiled, flat, thin piece of metal inside that builds up an electrical charge on one side and when it is full, discharges it all at once in a big zap. Don't get on the wrong side of that zap!
