Although the risk of electrical shock is indeed very low, the physical shock (i.e. fright) resulting from the bang or pop that often accompanies a high-current short can result in injury such as losing balance on a ladder or jerking ones hand into moving machinery. If you are working in an enclosed area such as the bilge of a boat which may contain combustible fumes (gasoline or hydrogen from batteries) the heat/spark can also lead to ignition. -p. --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
