Actually, I knew where he was going, but it was the "only" the negative which I wanted him to clarify. Also, just touching those with your body even with a wristwatch on will not cause one bit of a problem. The resistance of your body / skin is high enough that a 12v source will not even cause you a tingle. This is one of the reasons they stick with the inefficiencies of low voltage in auto and marine applications. But, swing a wrench around and contact some grounded metal while disconnecting the positive lead (with the negative one still connected) and watch the sparks fly. > > P.S.

So therefore > could be described as like. ;-) Yes, "like 5 min" is 'merican slang for "approximately 5 minutes or so, old chap", but like, I didn't say that man... It was some other dude. ;-) -Fred W
