Hence the emoticon, I just find it a bit odd sometimes when people write in the same manner they would speak. Don't get me wrong, I'm from good old Blighty, and I certainly don't have a great grasp of written English! After all I never used to be able to spell Engineer, now I is one..... Regarding +ve/-ve order, sorry but I cannot agree on the low voltage not causing you any harm. Given the right conditions you can actually get a nasty jump off a good battery, and yes, even a burn. It is after all the amps that get you. I also forgot to mention possible petrol ignition from the ensuing spark. Anyway it's academic really as you were of course only questioning the "only" bit of the statement. Cheers Al
